具有死区非线性补偿的广义预测控制

Generalized predictive control with dead nonlinearity compensation

讨论了具有死区非线性特性和白噪声干扰的系统的GPC控制问题。先对无死区的线性系统设计GPC控制算法 ,然后根据期望得到的线性部分输入u(k)重构最终的控制器输出u (k) ,使得相应的u (k)恰好补偿死区R的影响 ,控制器的输出总是大于死区R的宽度。仿真结果证明了该方法的有效性。

In this paper,GPC arithmetic is designed at first for linear system without dead-time,and the final output u *(k) of the controller is re-constructed then,according to the prospective input u(k) of the linear part.The question in GPC of the system with dead nonlinearity and white noise disturbance is discussed.The results of the simulation demonstrate the effectiveness of this method.
