| 摘 要： | 针对常规PID控制器不能很好兼顾抗干扰性与鲁棒性以及基于模型的控制算法过于依赖受控系统数学模型的缺点,提出一种适用于离散时间多输入多输出(MIMO)非线性系统的无模型自适应控制算法.该算法首先通过偏格式线性化方法将非线性系统线性化,再利用一种新型的投影算法在线辨识受控系统参数,根据辨识得到的受控系统参数直接递推计算无模...

| Abstract: | To solve the shortcomings of traditional PID controllers in dealing with disturbance rejection and robustness,and the over-reliance of model-based control algorithms on mathematical model of the controlled system,a model-free adaptive control algorithm is proposed for discrete time MIMO(multiple-input multiple-output) nonlinear systems.In this algorithm nonlinear system is linearized by linearization of partial format.Then the controlled system parameters are identified on-line by a novel projection algorit... |
