| 摘 要： | 针对工业控制领域中非线性系统的模型辨识与预测控制问题,采用最小二乘支持向量机回归方法构造非线性函数,运用状态子空间（N4SID）模型辨识方法辨识非线性状态空间模型.在此基础上建立非线性预测控制器,利用拟牛顿算法进行非线性预测控制律的求解,从而实现了一种新的基于支持向量机N4SID辨识模型的非线性预测控制算法.仿真实验验证了该算法的有效性和可行性.

| Abstract: | To the problems of the model identification and predictive control of nonlinear systems in the domain of industry control,a nonlinear model predictive control algorithm is presented.The nonlinear function is constructed by least squares support vector machines regression.A numerical algorithm for subspace state space system identification is utilized to identify a nonlinear stat-space model,which is used to construct a nonlinear model predictive controller.In deriving the control law,a quasi-Newton algorithm is applied to implement the nonlinear model predictive control(NMPC) algorithm.The simulation result shows the validity and feasibility of the NMPC algorithm. |
