Abstract:

The design and testing of a high-bandwidth continuous actuator for aeronauticalapplications is presented hereinafter. The actuator has a dual goal of controlling both the aeroelasticbehaviour and the flight mechanics of the model in which it is installed. In order to achieve theseaims, the actuation bandwidth of the active aerofoil, as well as its static camber variation, have to besufficiently high. The camber morph is achieved by using tailored piezoelectric patches in a sandwichconfiguration with a linear trailing edge slider to allow the necessary compliance. The morphingactuator is design

Abstract:

In many dynamic systems, such as vehicles, engine air and fuel control systems, fluid power systems, industrial robotics, and testing machines, high-speed actuators are necessary to achieve efficient system operation and high bandwidth performance. This article introduces a new actuation mechanism to enable high-speed actuation. The premise for this actuation mechanism is to momentarily couple a moving component (kinetic energy source) with translational components, which is enabled by a coupling/clutch system. The kinetic energy source (flywheel, electric motor, pump or motor shaft, etc.) is

Abstract:

Restricted by narrow bandwidth of the existing high-flow servo valves, dynamic performance of high-flow electro-hydraulic servo systems can only be enhanced to a certain extent by advanced control algorithms. This paper proposes a new hydraulic control circuit, in which two valves are arranged in parallel to control the actuator jointly. Frequency response of the equivalent valve is raised and thereby the performance of high-flow electro-hydraulic servo systems can be improved. A model of the proposed system is built and the principle of improving system dynamic performance using the new circu

Abstract:

A micro silicon cantilever actuated by ZnO thin film was designed, fabricated and characterized. The ZnO thin film was deposited by RF sputtering at room temperature. The transverse piezoelectric constant d31 was found to be-4.66 pC/N. Time and frequency responses of the cantilever actuator were investigated by means of a laser Doppler vibrometer. The actuator has a sensitivity of 12 nm/V at 15 kHz. Its 1st bending resonance was observed at 53 kHz. The bandwidth was found to be 27 kHz with damping of 0.35%. The cantilever demonstrated capability of high frequency actuation on a nanometer level

Abstract:

In modern times, the design and optimization of different actuator systems for controlling a high-precision position control system represent a popular interdisciplinary research area. Initially, only single-stage actuator systems were used to control most of the motion control applications. Currently, dual-stage actuation systems are widely applied to high-precision position control systems such as hard disk drive (HDD) servo systems. In the dual-stage system, a voice coil motor (VCM) actuator is used as the primary stage and a piezoelectric micro-actuator is applied as the secondary stage. H

Abstract:

This thesis is concerned with issues relating to the development of an active sealing system for hydraulic actuators where the sealing elements can be radially extended and retracted to vary the friction and leakage characteristics. In order to determine the feasibility of the active sealing concept it is necessary to establish that varying the seal geometry may achieve useful improvements in the friction-leakage trade-off and that a practical method of achieving this seal extension can be realised. Experimental and simulation approaches for seal friction prediction have been developed and act

Abstract:

The predictive design of fuel injection hardware used for active combustion control is not well established in the gas turbine industry. The primary reason for this is that the underlying mechanisms governing the flow rate authority downstream of the nozzle are not well understood. A detailed investigation of two liquid fuel flow modulation configurations is performed in this thesis: a piston and a throttle-valve configuration. The two systems were successfully built with piezoelectric actuation to drive the prime movers proportionally up to 800 Hz. <p>Discussed in this thesis are the importan

Abstract:

High-bandwidth fuel modulation is currently one of the most promising methods for active combustion control. To attenuate the large pressure oscillations in the combustion chamber, the fuel is pulsed so that the heat release rate fluctuations damp the pressure oscillations in the combustor. This thesis focuses on the development and implementation of a high-bandwidth, proportional modulation system for liquid-fuel active combustion control. The throttle valve modulation system, discussed in this thesis, uses a 500-um piezoelectric stack coupled with an off-the-shelf valve. After comparing th

Abstract:

This last decade experienced a sudden increase of interest in the control of thermo-acoustic instabilities, in particular through the use of fuel modulation techniques. The primary goal of this research was to design, construct and characterize a high bandwidth proportional fuel injection system, which could be used to study the effect of specific levels of fuel modulation on the combustion process and the reduction of thermo-acoustic instabilities. A fuel injection system, incorporating the use of a closed loop piston and check valve, was designed to modulate the primary fuel supply of an

Abstract Vibratory load transmission reduction for precision space A major challenge to the aerospace industry is to develop precision beam steering optics with clear aperture as large as 8 inches that operate at bandwidths of 1KHz, have throws of 3–10 mrad, and position accuracy of 100 nrad. The proposed technology promises to meet these requirements by introducing a new piezoelectronically driven colocated sensoriactuation system.

In this research, a new approach is proposed to enhance the effectiveness of piezoelectric actuators without the trade off between force and stroke. Through mechanical tailoring, the resonant frequencies of the actuation system (includes the piezoelectric actuator and the related mechanical and the electrical elements for actuation) can be tuned to the required actuation frequencies. This obvious will increase the authority (both stroke and force) of the actuation system. However, resonant actuation system could be hard to control and non-robust, due to its narrow operating bandwidth. This iss

The objective of this research is to address some of the important design issues of the recently developed piezoelectric resonant actuation system (RAS) concept. The RAS is achieved through both mechanical and electrical tailoring.

This obviously will increase the authority of the actuation system. To further enhance controllability and robustness, the actuation reso

In the last decade, Lead Zirconate Titanate Oxide (PZT) thin-film actuators have received increasing attention because of their high frequency bandwidth, large actuation strength, fast response, and small size. The PZT film thickness is usually less than several microns as opposed to hundreds of microns for bulk PZT patches that are commercially available. As a result, PZT thin-film actuators pose unique vibration issues that do not appear in actuators with bulk PZT. Two major issues affecting actuator performance are the frequency bandwidth and the resonance amplitude. As an electromechanical

Abstract:

Efficient high-speed on/off valves are a critical technology for enabling digital control of hydraulic systems via pulse-width-modulation (PWM). High-speed valves, when used in virtually variable displacement pumps (VVDP), increase system bandwidth and reduce output pressure ripple by enabling higher PWM frequencies. Our approach to achieving high speed and large flow area with low actuation power is a unidirectional rotary valve designed specifically for PWM. In comparison to conventional valves, the rotary valve reduces valve actuation power from a cubic dependence on PWM frequency to a squa

The test article was designed to pivot the forward portion of the round about the aerodynamic center (which was collocated with the forward section center of gravity). While effective in trim articulation, the majority of actuator power was expended resisting nose inertia rather than manipulating air loads. Adaptive ac
