摘　　要：针对H_∞控制器阶数较高的问题,提出一种基于平衡截断的方法,降阶后的控制器满足信息损失最小理论。降阶后的闭环控制系统满足控制性能要求,能有效地控制系统误差。最后对两个H_∞控制器降阶进行仿真,并与已知方法进行比较研究,仿真效果证明了所提方法的有效性和可行性。Aiming at the problem of high order of controllers,a balanced truncation method was proposed.The reduced order controller satisfied the minimum information loss theory.The closed-loop control system can meet the control performance requirements and can effectively control the system error.Finally,the two controllers were simulated and compared with the known methods.The simulation results proved the effectiveness and feasibility of the proposed method.
