【摘要】 针对连续时间非线性仿射输入系统,提出了一种基于反馈线性化的构造性模型预测控制(MPC)策略。首先采用反馈线性化方法和Raccati方程,构造了系统的一个控制Lyapunov函数,进而建立系统的一个稳定控制类。其次,结合构造性主动控制思想,设计相应的模型预测控制策略。最后,以化工过程连续搅拌反应器(CSTR)为例,仿真验证本文结果的有效性。更多还原

【Abstract】 A constructive model predictive control(MPC) scheme is proposed for continuous-time nonlinear affine-input systems,based on feedback linearization of the system.Firstly by using the feedback linearization method and Raccati equation, a control Lyapunov function(CLF) of the system is constructed.This then established a stable control class of the system. Secondly a MPC strategy is designed by combination of constructive active control idea.Finally,the simulation of continuous stirred tank reactors(CSTR) in chemical processes is used to illustrate the effectiveness of the results presented here.更多还原
