This paper works on the concept of flatness and its practical application for the design of an optimal transient controller in a synchronous machine. The feedback linearization scheme of interest requires the generation of a flat output from which the feedback control law can easily be designed. Thus the computation of the flat output for reduced order model of the synchronous machine with simp...

A stepper motor is usually operated in position open-loop control for simplicity. However, order to improve the transient and steady-state performances of motor-based drive system, a high performance system designed feed encoder signal back form closed-loop such as general servo drive, high-performance speed loop controller can then be used overcome nonlinear characteristics motor, cogging forc...

This paper investigates the problem of robust output regulation control with prospected transient property for strict feedback systems. By employing internal model principle, a can be transformed to stabilization new constraint. Then, by constructing speed function and adopting barrier Lyapunov technique, dynamic controller designed not only drive error closed-loop system entering into prescrib...

Motivated by closed-loop flow control applications, a new formulation of the proper orthogonal decomposition (POD) is presented which is capable of characterizing not only the controlled and natural states of a given flow but also the transient behavior between these states. This approach, which is termed temporal POD (TPOD) extracts the optimum frameof-reference and the temporal information re...

The Static Synchronous Compensators (STATCOMs) have been recoginzed as the most effective solution for dynamic reactive power compensation, voltage stability enhancement and subsynchronous resonance damping purposes in the electric power systems. The STATCOMs in the distribution utilites (DSTATCOMs) are increasingly investigated for dynamic reactive power compensation and power quality improvem...

to enhance the closed loop performance in presence of disturbance, uncertainties and delay a double loop mixture of mpc and robust controller is proposed. this double loop controller ensures smooth tracking for a 3-axis gyro-stabilized platform which has delay intrinsically. this control idea is suggested to eliminate high frequency disturbances and minimize steady state error with minimum powe...

This paper proposes a new discrete fuzzy-tuning current-vector control (FTC) scheme for three-phase pulsewidth modulation (PWM) inverters. The proposed current control scheme can achieve fast transient responses and, at the same time, have very low total harmonic distortion in output current during steady-state operation. The proposed FTC scheme generates quasi-optimum PWM patterns by using a c...

Abstract−This study mainly focuses on the development of an automatic fuzzy control (AFC) system for a parallel dc-dc converter, and the control objective is to achieve the stable voltage regulation and uniform current distribution. The average model for an example of a three-module boost converter, which is composed of three conventional boost converter frames in parallel connection, is derive...
