摘　　要：设计了针对一类具有非匹配不确定性的非线性大系统的分散变结构控制器,将反演控制理论、块控原理和变结构控制理论相结合,处理系统中的非匹配不确定性,有效改善系统的动态性能。将所研究的分散变结构控制方法,应用于多机电力系统的励磁控制中,使含有不确定参数的非线性系统在外扰动的情况下具有很好的鲁棒镇定性。给出了控制器设计过程。对两区域四机系统进行仿真,结果表明,所设计的分散变结构励磁控制器能够使系统受到扰动后快速稳定,兼顾提高稳定性和增强系统鲁棒性的优点。A decentralized variable structure controller is developed for a nonlinear uncertain large scale systems.Adaptive back stepping control method,block control approach and variable structure control are combined to effectively deal with unmatched uncertainties and effectively improve dynamic performance of the system.The developed decentralized variable structure controller has applied to excitation control of multi-generator power system,the proposed control scheme can achieve good control performances and robustness under the unmatched uncertainties and unknown external disturbance.The design procedures are also given in this paper.The simulation results of the two-area four-generator power system show that the developed controller not only restrains the power oscillation quickly,but also improves the system stability effectively and possesses good robustness to disturbance.
