作者：韩云瑞

This paper studies the nonlinear variable structure control (VSC) technique for designing power system integrate control systems which include an excitation controller and fast valve controller.A new method is applied to find nonlinear switching surface in deriving the control *** responses to various large perturbation are *** simuulation results show that the nonlinear VSC technique for integrated control systems can considerably improve the transient stabilization limitation of power systems and improve the dynamic properties of the generators.

A variable structure control system (VSCS) yields total or selective invariance to system parameter variations and disturbances when in the sliding mode. In order to prescribe the system performance, a model-following approach to VSCS design is used. The required behaviour is achieved by defining a model with ideal response characteristics, and a VSCS is designed so that the error between the plant and the model is forced to exhibit a sliding mode. A parameter insensitive controller with improved disturbance rejection which achieves desired system performance results. The resulting nonlinear scheme cannot be assessed using conventional frequency domain techniques. A new analysis tool is therefore proposed and used to explore the robustness of such a nonlinear control scheme. The design technique is illustrated for lateral multimode control. The aircraft system requires a parameter insensitive control type with improved disturbance rejection if possible. In addition, the ability to prescribe flying quality requirements directly is important. The problem thus provides a suitable challenge for the technique. The robustness analysis is illustrated using the resulting VSCS applied to a range of realistic perturbation models of the fully nonlinear aircraft model.
