摘要
针对一些非线性系统的模型辨识和预测控制计算繁琐的问题,提出基于快速正交搜索算法的预测控制方法,可准确地对非线性系统模型进行辨识。该方法优化了计算方法,省去了繁琐的迭代过程,并减少了每次迭代过程中引入的误差。利用辨识模型建立预测模型,对非线性系统进行直接预测控制。仿真实验结果证实了该方法的有效性和可行性。
Considering the complicated calculation in some nonlinear system ’s identification and prediction control,the predictive control method based on fast orthogonal search algorithm was proposed to identify the nonlinear system model accurately.This method can optimize calculation method,simplify iterative process and reduce the error introduced by each iteration process.The identification model was employed to build pre-diction model so as to accurately identify the nonlinear system model.Simulation results prove both effective-ness and feasibility of this method.
