Abstract:

Since the energy crisis, the further development of a variable speed pump-controlled hydraulic system driven by an electric machine has attracted increasing attention during the past few years. As a response to this, an innovative double pump-controlled asymmetric cylinder system (DPC) and its control method are proposed in this study. The purpose of this study is to investigate the performance of two variable speed pump-controlled systems for asymmetric cylinders under a four-quadrant operating condition, in comparison with single pump control (SPC). The four-quadrant operating principles of the two systems are analyzed by simulation. Simulation models for both systems are introduced, and a position control method is proposed, with a tracking differentiator and speed feedforward, plus proportional-integral-derivative (PID) for four-quadrant operation. The DPC model was validated with the measurement of a crane. The simulations using the validated model were performed with a position reference and a varying load (four-quadrant operating arm of an excavator). The results demonstrated that the velocity fluctuation is eliminated by using the DPC instead of the SPC, and the position control performance of the DPC is better compared to the SPC, although the energy efficiency decreases slightly. Hence, the proposed DPC and its position control method are feasible for the four-quadrant operation of asymmetric cylinders.

Abstract:

Brushless DC motors, which are applied to the human skeleton boosters, require frequent switch of four-quadrant operation states of forward rotation, backward rotation, electro motion and braking control. This switch generally requires to be soft and smooth without overshoot, big impulse or speed mutation. The general performance of the brushless DC motor control system cant meet this requirement. The main purpose of this paper is to solve this problem by adopting bipolar PWM control which makes it possible to realize the motor operating in four-quadrant and improve its characteristics. In addition, the paper proved the correct and efficiency of this method by using simulation .

Abstract:

Coleman and Moon demonstrated a traffic engineering-based design methodology to determine gate delay (length of flashing signal operation prior to entry gate descent) and gate interval time (time period between initiation of descent of entry gates and initiation of descent of exit gates) at four-quadrant gate crossings. A simulation model incorporating this traffic engineering-based design methodology was developed for the Illinois Department of Transportation to assist in establishing four-quadrant gate operating parameters. To assist in validating the four-quadrant gate simulation model, a comparison of the gate operating parameters at a recent installation in North Carolina was undertaken. The findings from the comparison indicate there is close agreement with the values used in the field installation and those determined by the simulation model.

Abstract:

The DC-DC converter find a wide scope in industries, telecommunication sectors, power electronics area, etc. Nowadays bi-directional converters have a higher end over them since the energy from the load during regenerative braking is fed back to the source, thus obtaining energy efficient system. A single topology that can provide Buck-Boost operation with positive output having four quadrant operations is not available in the literature. A common limitation of power coupling effect in some known multiple-input dc-dcconverters has been addressed in many kinds of literatures. In this paper, a new single topology of two quadrants DC-DC Sepic converter has been developed to provide four quadrant operation of a high- frequency dc-dc converter having one supply source and proper control of the converter. The combined topology has been analyzed and studied by spice simulation.

Abstract:

<p>In step with development of advanced, cost effective semiconductors and electrical motor drive components, the Switched Reluctance Machine (SRM) has become the center of public attention. Interest in a single-phase SRM has arisen in many places, especially because of its low cost applications. However, some drawbacks have plagued single-phase SRM: the lack of self-starting capability and restricted operation conditions.</p><p> This thesis presents a four-quadrant operation SRM drive system with a single controllable switch for two phase configuration. The SRM's configuration has four main stator poles, four rotor poles, and four auxiliary stator poles. Because of this special arrangement, a four-quadrant operation with a given power converter topology and proposed control algorithms has been realized. The focus of the paper is to realize a four-quadrant operation with a single-switch converter based SRM. In addition, this research resulted in a new self-starting scheme without adding permanent magnets. Simulation results and experimental results utilizing the control algorithm verify the performance of the system.</p><br>Master of Science

Abstract:

In the emergence of switched reluctance motors to the commercial market, two-phase motors have received relatively little attention. Higher power and industrial applications have focused on the use of three and occasionally four phase machines, while low cost applications demanding only modest performance have largely been the domain of single phase machines. By contrast, while two phase systems have been the subject of occasional studies, they have not been widely applied.<p> <p> Two phase systems represent a compromise between the higher cost but higher performance three phase machines, and the lower cost but lower performance single phase systems. They do not suffer from the same magnitude of peak to peak torque ripple that single phase machines experience due to their wide zero torque arcs. Yet two phase systems keep a relatively low component count in their power-converter designs. The primary drawback to two phase motors is the difficulty of torque production at startup speeds. Although sizably reduced from single phase machines, the zero torque regions in two phase machines can still result in rotor lock unless steps are taken to circumvent them. These steps can include measures such as: placement of permanent magnets or other means to ensure the rotor is positioned outside of these zero torque regions when at rest, mechanically spinning the motor before energizing the phase windings on startup, shaping of the rotor or stator poles to extend the positive torque regions of each phase, or use of the machines mutual inductance with both phases energized to produce enough torque to initiate motion.<p> <p> This project is intended to develop a variable speed controller for a 4:6 two-phase switched reluctance motor. The motor is to operate in all four quadrants, and is to demonstrate self starting capability. The controller is also supposed to produce signals needed to operate the motor with multiple converter designs. Two different converter designs will be built and tested with the converter. One makes use of a single switch and two diodes per phase, the other has one switch and one diode per phase plus a common switch and common diode shared by all phases.<p> <p> There are many possible applications of the system being developed in this project. Any application needing four quadrant operation while still being constrained by low cost requirements would be ideal. Some examples include washing machines, power tools, and low power industrial applications.<p><br>Master of Science

Abstract:

<p>Speed and position control systems for marine vehicles have been subject to an increased focus with respect to performance and safety. An example is represented by drilling operations performed with semi submersible rigs where the control of position and heading requires high accuracy. Drifting from the well position could cause severe damage to equipment and environment. Also, the use of underwater vehicles for deep ocean survey, exploration, bathymetric mapping and reconnaissance missions, has become lately more widespread. The employment of such vehicles in complex missions requires high precision and maneuverability.</p><p>This thesis focuses on thrust estimation and control of marine propellers with particular attention to four-quadrant operations, in which the propeller shaft speed and the propeller inflow velocity (advance speed) assume values in the whole plane. In the overall control system, propellers play a fundamental role since they are the main force producing devices. The primary objective of the thruster controller is to obtain the desired thrust from the propeller regardless the environmental state. During operations, propellers are often a¤ected by thrust losses due to e.g. changes in the in-line water velocity, cross flows, ventilation, in-and-out of water effects, wave-induced water velocities, interaction between the vessel hull and the propeller and between propellers. Propellers may thus work far from ideal conditions. Therefore, the knowledge of the propeller thrust and torque, together with forces induced by the interaction between the vehicle and propellers and between propellers, is fundamental to achieve high control performance. Unfortunately a propeller system is usually not equipped with thrust and torque sensors, therefore thrust losses are not directly measured.</p><p>Motivated by this, a new four-quadrant thrust estimation scheme is presented, extending previous results valid for propeller operating in two quadrants. Based on shaft speed and motor torque measurements, the scheme involves a nonlinear observer for the propeller torque that shows stability and robustness for bounded modeling and measurement errors. The propeller thrust is computed as a static function of the propeller torque. The performance is demonstrated in experimental tests, showing improved accuracy in the thrust reproduction with respect to the direct use of the four-quadrant propeller characteristics.</p><p>A nonlinear observer for the torque loss estimation, similar to the one implemented in the thrust estimation scheme, is included in a new fourquadrant nonlinear thrust controller, designed for calm and moderate sea conditions. The control strategy is based on a shaft speed controller where the desired velocity is computed from the desired propeller thrust and on the torque losses. Experimental results are provided, demonstrating the e¤ectiveness of the new controller with respect to the conventional shaft speed and torque controllers.</p><p>The thrust controller, designed for calm and moderate sea conditions, is subsequently improved by including an anti-spin strategy to reduce power peaks and wear-and-tear in extreme sea conditions. The anti-spin strategy is derived from previous works that were designed for Dynamics Positioning (DP) operations. The presented controller can operate also for maneuvering and transit operations, where the vehicle speed is larger than in DP operations. The performance of the controller is validated by experimental tests.</p><p>Motivated by environmental issues and the need of reduced fuel consumption and CO<sub>2</sub> emissions, a novel control scheme for improving, in moderate sea, the propulsion e¢ ciency with respect to conventional propeller controllers is presented. The main idea is to exploit the variation in the advance speed due to waves to increase the average propulsion efficiency without reducing the vessel speed. A nonlinear controller is proposed showing that, theoretically, is possible to increase the propulsion efficiency. Model tests determine dynamic characteristics of propellers in waves and a simulation is employed to validate the novel control scheme.</p>

Abstract:

It has been shown in previous investigations that when all combinations of both positive and negative direction of rotation and flow direction are allowed in operating a multistage axial flow compressor, the operating point may be in any of the four quadrants of the pressure rise versus flow characteristic. The present paper is the first discussion of the flow field of all possible modes of operation of an axial flow compressor. During the present study interstage time dependent hot film velocity measurements and five hole pneumatic probe measurements were combined with steady and time dependent CFD solutions to investigate the flow fields in the three-stage axial compressor. Results are presented in terms of mean-line velocity triangles, mean stream surface plots, mid-span radial velocity contours right through the compressor, rotor-downstream radial distributions of axial and tangential velocity, stator-downstream axial velocity contours and mid-span entropy contours through the compressor. Main flow features are pointed out and discussed. The study was instigated in an effort to understand possible accident scenarios in a three-shaft closed cycle nuclear powered helium gas turbine.
