In order to conquer uncertainty and disturbance, a reduced robust control strategy based on linear matrix inequality (LMI) was proposed for a proton exchange membrane fuel cell (PEMFC) system. And then the structure singular value (SSV) μ analysis method was utilized to testify the robust stability of proposed controller. The simulation results demonstrated that the control method could maintain the...
Control design for variable speed wind turbine system is one of most challenge to engineer today. Wind energy conversion system that includes complex combination of aero dynamics and electrical phenomena together with anonymous action of wind speed making control system sophisticated. Beside the nonlinearity model of wind turbine, the basic control strategy for wind turbine is maximizing the power...
Various nonlinear control techniques have been applied in power system control. The performance of nonlinear controllers is influenced by the parameter uncertainty and external disturbance. This paper will present a novel approach of robust variable structure control (VSC) based static synchronous compensator (STATCOM) controller design for damping multi-mode electrical-mechanic oscillations. The...
This paper presents a global control strategy for multi-machine power systems to enhance transient stability. The global control system models are proposed to represent the power systems with abrupt structure changes. Multi-machine power systems are first represented by interconnected subsystems with uncertainties and nonlinearities. Then each subsystem is decomposed into four nonlinear partial systems...
In this paper, an H-infinity load-frequency controller for a power system generator will be designed without the knowledge of the system model. Uncertainty in the system model is a common problem in power systems. In this paper the strategies for discrete-time linear system quadratic zero-sum games related to the H-infinity optimal control problem are solved forward in time without knowing the system...
In the last decade, various nonlinear control techniques have been applied in FACTS controller design. The performance of nonlinear controllers is influenced by the parameter uncertainty and external disturbance. This paper mainly discusses a novel approach of robust variable structure control (VSC) based series FACTS controller design for damping local mode power system oscillations. The VSC-based...
