摘要
针对非自衡对象，提出一种完全干扰解耦控制方法，克服了以往方法的缺陷．方法中引入了一个局部回路使系统干扰响应和参考输入响应解耦，并通过一个适当的最小阶频域观测器来保证零稳态误差．新方法的优点是系统具有快的参考输入响应和很好的干扰抑制能力，系统的整定非常方便，参考输入响应和干扰响应可分别通过一个参数来调节．给出了设计实例来说明新的设计方法，并与以往的设计方法进行了比较．仿真结果表明，新方法具有较好的性能和鲁棒性．
A new design method is presented for control of selfirregulating plants which overcomes the limitation of the previous methods. In the new scheme an inner loop is introduced which makes the disturbance response decoupled from the setpoint response, and a minimum order frequancy domain compensator is added to guarantee the zero steady state response. The important merit of the new method is that it provides fast setpoint response and good disturbance rejection capability, and both the setpoint response and disturbance response can be adjusted by two paramemters respectively. Examples are given to illustrate the new method. The simulation results show that the new method is superior to those cited in this paper.
