【摘要】 对于二阶van der Pol混沌系统,采用不同的趋近律设计滑模控制器进行平衡控制。在滑模控制器的设计中,分别采用指数趋近律和快速幂次趋近律。采用指数趋近律时,控制输入出现了抖振现象。采用快速幂次趋近律时,控制输入没有出现抖振现象。通过MATLAB/Simulink软件建立采用不同趋近律的滑模控制仿真实验。该仿真实验,有助于学生对混沌控制和滑模控制的理论理解和工程应用。更多还原

【Abstract】 For two order van der Pol chaotic system, different reaching laws are used to design sliding mode controllers for the balance control of the chaotic system. In the design of sliding mode controller, exponential reaching law and fast power reaching law are adopted respectively. When the exponential reaching law is adopted, chattering phenomenon occurs in the control input. When the fast power reaching law is adopted, there is no chattering phenomenon in the control input. A sliding mode control simulation experiment with different reaching laws is established through MATLAB/Simulink software. This simulation experiment helps students understand the theory of chaos control and sliding mode control and engineering applications.更多还原
