Abstract:

A novel and robust field oriented vector control method for standalone induction generators (IG) is presented. The proposed controller exploits the concept of direct field orientation and provides asymptotic rotor flux modulus and DC-link voltage regulations when a DC-load is constant or slowly varying. Flux subsystem, designed using Lyapunov’s second method, has, in contrast to standard structures, closed loop properties and therefore is robust with respect to rotor resistance variations. A decomposition approach on the base of the two-time scale separation of the voltage and torque current d

Abstract:

A mobile satellite communication antenna is a device installed on a moving carrier for mobile satellite communication. Gimballed motorized pedestals are used to eliminate the effect of disturbance and maintain uninterrupted communication when the carrier is moving. Mobile satellite communication antennas are becoming increasingly more popular due many advantages of mobile satellite communication. In this paper, a three-axis ship-mounted antenna on a pedestal gimbal system is studied. We study the problem with a different perspective and method from the previous work for two-axis antenna pedest

The authors have designed a gyro-system for orientation (guidance) and stabilization, with two gimbals and a rotor in magnetic suspension (AMB—Active Magnetic Bearing) usable for self-guided rockets. The gyro-system (DGMSGG—double gimbal magnetic suspension gyro-system for guidance) orients and stabilizes the target coordinator’s axis (CT) and, at the same time, the AMB–rotor’s axis so that they overlap the guidance line (the target line). DGMSGG consists of two decoupled systems: one for canceling the AMB–rotor translations along the precession axes (induced by external disturbing forces), th

This paper studies the finite-time stability problem of a class of switched nonlinear systems with state constraints and control constrains.

For the whole switched nonlinear system, a suitable switched law is designed to ensure the following: (1) at the time of the transition, Lyapunov function’s value of the switched-in subsystem being less than the value of the last subsystem; (2) the

This paper presents the design of an autopilot for the flight mode transition in a hybrid quadrotor/fixed-wing aircraft known as QuadPlane. The autopilot includes an attitude stabilization subsystem, a control subsystem for takeoff and landing in quadrotor mode, and a control subsystem to regulate the longitudinal speed of the aircraft and determine the transition from quadrotor to fixed-wing and vice versa. During pure fixed-wing and quadrotor modes, the pilot has control authority on the QuadPlane. The proposed scheme is validated using the X-Plane flight simulator.

This paper studies the problems of incremental passivity, incremental passification and incremental stabilization for a switched nonlinear system. First, an incremental passivity concept for switched nonlinear systems is proposed. Each subsystem is only required to be incrementally passive, when it is active.

Second, a state-dependent switching law and state feedback controllers are designed to render a system with relative degree one incrementally

When there exists at least one uncontrollable subsystem, a sufficient condition is also given to guarantee the stabilization of the switched impulsive system under appropriate switching signal.

Abstract:

A quantum-classical model of cis-trans photoisomerization of the visual pigment rhodopsin chromophore was investigated in wide ranges of parameters. The quantum subsystem of the model includes three electronic states for rhodopsin: the ground state, the excited state, and the ground state of primary photoproduct. The local temperature of the mass points of the classical subsystem was used as a main reference quantity. The best agreement with experimental data was shown to be in the range of moderate temperatures in agreement with the Raman spectroscopy data. The essential role of a quick trans

Abstract:

The stability analysis and stabilization of Takagi-Sugeno (T-S) fuzzy delta operator systems with time-varying delay are investigated via an input-output approach. A model transformation method is employed to approximate the time-varying delay. The original system is transformed into a feedback interconnection form which has a forward subsystem with constant delays and a feedback one with uncertainties. By applying the scaled small gain (SSG) theorem to deal with this new system, and based on a Lyapunov Krasovskii functional (LKF) in delta operator domain, less conservative stability analysis

Abstract:

This paper gives a method for static output feedback stabilization of linear time invariant systems. A general solution of a matrix equation concerning system parameter matrices is used to construct a state coordinate transformation. Then, the closed-loop system is equivalent to a transitional form, whose pivotal isolated subsystem can be stabilized via a gain matrix. This gain matrix is the free variable of the general solution. Furthermore, using this general solution of the matrix equation, the original problem is reformulated to a low dimension system, which can be easily solved. Numerical

Abstract:

This article investigates the robust stabilization problem for nonlinear time-delay systems with dead-zone input and complex dynamics. By flexibly using the inequality technique, the backstepping control method, and skillfully introducing a new Lyapunov–Krasovskii functional, we obtain a stable controller without using unmeasurable signals in the dynamic subsystem. The control system is guaranteed to be stable finally. Two simulation examples are given to verify the control strategy.

In this paper, we present the design for a decentralized control method comprising a series of local state feedback controllers for a class of linear fractional composite systems. In addition, the corresponding asymptotic stabilization criterion is derived. First, we design the local state feedback controllers for each subsystem of the linear fractional composite system. Then, based on the vector Lyapunov function, we combine these local state feedback controllers into a single decentralized controller through which the asymptotic stabilization criterion is proposed for the class of linear fra

Abstract:

As an interconnected power system via a High-Voltage Direct Current (HVDC) link is subjected to a rapid load change with the frequency of inter-area oscillation mode, system frequency and tie line power may be severely disturbed and oscillate. To compensate for the rapid load change and stabilize both frequency and tie line power oscillations due to the inter-area mode, the dynamic power flow control via a HVDC link can be exploited. To implement this concept, a new design method of HVDC-based controller is proposed. To grasp a physical characteristic of the inter-area oscillation frequency, t

Abstract:

The purpose of this research is to develop an intuitive interface to control rescue robots. We propose a new image stabilization system for operating rescue robots easily. The use of teleoperated rescue robots is promising in searching for victims in rubble. In the rescue activities with such robots, operators control the robots remotely through images captured by cameras mounted on the robots. Since the orientation of the robots change rapidly while they move in rubble, image stabilization is necessary so the operators can search for victims without suffering from fatigue or motion sickness.

Abstract:

In this paper, a general approach for robust partial stabilization of uncertain non-linear systems is presented. In this approach, the non-linear dynamic system is divided into two subsystems, called the first and the second subsystems. This division is done based on the required stability properties of the system’s states. The reduced input vector (the vector that includes components of the input vector appearing in the first subsystem) is designed to asymptotically stabilize the first subsystem. The proposed scheme is then applied for designing a guidance law as a potential application. Inde

This paper addresses a composite two-time-scale control system for simultaneous three-axis attitude maneuvering and elastic mode stabilization of flexible spacecraft. By choosing an appropriate time coordinates transformation system, the spacecraft dynamics can be divided into double time-scale subsystems using singular perturbation theory (SPT). Attitude and vibration control laws are successively designed by considering a time bandwidths separation between the oscillatory flexible parts motion describing a fast subsystem and rigid body attitude dynamics as a slow subsystem.

Evolution of the orientation structures of polyacrylonitrile (PAN) precursors during thermal stabilization was investigated on the basis of in situ temperature-dependent measurements including synchrotron wide-angle X-ray diffraction and polarized infrared spectroscopy. The results indicated that the Hermans orientation factor of PAN crystallites increased firstly and then decreased in the process of stabilization, while the orientation of molecular chains showed a two-stage decrease. These were mainly attributed to the thermal relaxation of molecular chains and the cyclization reactions, whic
