| 摘 要： | 针对一类非线性系统, 将其等价为时变线性系统, 然后用三次样条函数逼近时变系数, 利用梯度算法在线辨识多项式的系数以实现时变系统的参数估计, 最后运用广义预测控制策略, 实现了对原非线性系统的自适应预测控制. 仿真结果表明了所提方法的有效性.

| Abstract: | An adaptive predictive control is implemented for a class of nonlinear system by substituting it with a time_varying linear system firstly, then a group of cubic spline functions are used to approach the time_varying coefficients and gradient estimation algorithm is used to identify the invariable coefficients of the polynomial on_line. At last, generalized predictive control is designed for the original nonlinear system. The effectiveness of the presented method is demonstrated by the simulation results. |
