| 考虑执行器的非线性, 研究了一种带补偿的逼近模型控制系统. 该控制系统包含逼近模型控制器与补偿器.逼近模型控制器根据对象的输入输出线性化关系直接得出控制律, 并由支持向量机辨识对象模型来实现. 补偿部分采用反馈环节来提高系统的鲁棒稳定性, 并采用在线估计得到的逆模型来抵消执行器的非线性特征. 文章分析了该控制系统的稳定性, 针对励磁系统的仿真实验验证了其有效性能. |
| 英文摘要 |
| Considering the actuator nonlinearity, a compensated approximate model-control(CAMC) strategy for the nonlinear plant is presented. This strategy includes the approximate model-controller and the compensator. The approximate model-controller is designed based on the approximate model which is obtained by linearizing the plant input-output relation and implemented by using support-vector-machine(SVM) modeling. In the compensator structure, a feedback filter is employed for ensuring the system stability and robustness; and an online estimated inverse model is used to compensate the actuator nonlinearity. The stability proof of CAMC is derived analytically. Simulations also show the effective application of CAMC to the excitation control in a power system. |
