摘要
基于Laguerre模型设计了一种自适应预测函数控制器.通过对闭环系统状态方程的稳定性分析,依据Lyapunov稳定性定理和奇异值理论得到控制系统稳定的必要条件.提出一种衰减因子校正方法,并使用遗传算法在线寻优调节衰减因子,以提高控制品质.仿真研究表明该控制算法稳定性强、在线计算量小.
An adaptive predictive functional control algorithm based on Laguerre model is designed. Performance of the closed-loop system is discussed, and robust stability condition is given based on Lyapunov stability theory. A parameter adjusting method is introduced. Genetic algorithm is applied to reduce online computation significantly and present strong robustness to parameters perturbation. Simulation results show the effectiveness of the method.
