摘要
非最小相位过程是较难控制的一类过程。针对一类自衡二阶非最小相位过程 ,采用内模控制系统结构 ,使系统具有良好的抗扰性和鲁棒性。给出了在希望的幅值和相角裕量下控制器参数的计算方法。设计例子与仿真结果表明 。
It is more difficult to design a non minimum phase process control system than to design a minimum phase one. In this paper, internal model control(IMC) system structure is adopted for second order non minimum phase processes and controller tuning method is presented based on gain and phase margin. Design instances and simulation results show that the systems designed with the proposed method have good stability and robustness.
