| 摘 要： | 对将线性系统的广义预测控制算法推广应用到非线性系统的控制问题进行了研究,即在每个控制周期内,递推预测非线性滞后系统在将来时刻的工作点,在工作点附近对非线性系统进行线性化,根据得出的线性化模型进行广义预测控制,并采用动态寻优的方法逐步逼近最优控制,仿真结果表明:非线性系统的广义预测控制算法能快速有效地跟踪系统的设定值,控制效果良好.

| Abstract: | This paper focused on extending the Generalized Predictive Control algorithm for linear systems to the nonlinear systems.At each control period,we predict the nonlinear system's future working point at which we linearize the nonlinear system and get a linear model of the nonlinear system,then we apply the Generalized Predictive Control algorithm to this linear model to control the nonlinear system and approach the optimal control by dynamic optimization.The simulating results show that the new Generalized Predictive Control algorithm for nonlinear systems can track the set value of the system rapidly and efficiently,and has good control results. |
