摘要
利用离散变结构控制理论对某型船舶电站设计了有功分配控制器。分析了抖振产生的原因并给出一种切换带厚度单调递减的改进型控制方案。仿真结果表明 ,所提方案较好地克服了困扰离散趋近律方法的稳态抖振问题 ,设计的有功分配控制器可以大大改善并联机组的动态特性 ,提高了并联系统的鲁棒性。
This paper makes valuable contributions on the design of the active power distribution controller for marine power station based on the discrete variable structure control theory.To eliminate the chattering in the steady state,an im proved control algorithm,which can resultin a monotonously decreasing switching band,is proposed.Simulation results have shown thatthe controller designed in this paper can improve dynam ic performances of the system effectively and enable the system to be robust.
