This article presents a voltage-modulated direct power control (VM-DPC) with an additional parallel compensator for the doubly fed induction generator under unbalanced grid conditions. The proposed method not only guarantees satisfying steady-state performance but provides also regulating property of negative-sequence output currents through designed compensator. It can provide symmetrical stat...

A new decoupling control structure is presented for complex industrial processes, which consists of a feedback controller, a decoupling compensator and a feedforward compensator for unmodeled dynamics. Using this structure, an intelligent decoupling control system is established which realizes an adaptive decoupling control strategy for industrial processes with integrated complexities by using...

in this paper, distributed parameter process systems behavior is studied in frequency domain. based on the dominant gain concept that is developed for such studies, a method is presented to control distributed parameter process systems. by using dominant gain concept, the location of open loop zeros, resulted from the time delay parameter in the process model, were changed from the right half p...

Over the past two decades, PC speeds have increased from a few instructions per second to several million instructions per second. The tremendous speed of today's networks as well as the increasing need for high-performance systems has made researchers interested in parallel and distributed computing. The rapid growth of distributed systems has led to a variety of problems. Task allocation is a...

Combined algorithms that include both variable structure system and identification approaches are proposed in this paper for guidance of UAV. The approach is based on the application of the so called ‘‘shunt’’ – parallel feedforward compensator. A similar approach based on the feedforward compensator for stabilization of plants of any relative degree was proposed by Bartolini et al. [1]. It is ...

AC transmission system is major part which links the generation and distribution.The transmission system is subjected to stability problems,which occurs due to abnormal conditions like faults,over voltages.These limit the transmission capability.Power systems often suffer from weakly damped swings between synchronous generators. The main objective of this paper is to enhance the transient stabi...

The passivity-based PD force control of a constrained one-link flexible arm is investigated using a linear distributed parameter model. In order to overcome the inherent limitations caused by the non-minimum phase nature of the noncollocation of the joint torque input and the tip contact force output, a new input induced by the measurement of root bending moment and a virtual contact force outp...

This paper mainly investigates fuzzy control with affine T-S delayed models, which can be applied to some nonlinear systems. Motivated from performing the linearization process associated with distinct operating points for nonlinear systems, an affine T-S fuzzy model with delayed state is addressed. The overall control then can be performed by the fuzzy inference mechanism, in which the consequ...
