Simulink软件在混沌系统滑模控制实验中的应用

Application of Simulink Software in Sliding Mode Control Experiment of Chaotic System

对于三阶Jerk混沌系统,采用滑模控制器进行平衡控制。在滑模控制器的设计中采用线性滑模面和指数趋近律。采用双曲正切函数代替符号函数,用于削弱抖振的影响。通过Simulink软件建立仿真实验系统,滑模控制器能够进行混沌系统的平衡控制。该仿真实验有助于学生对系统仿真、混沌控制和滑模控制的理论理解和工程应用。

For the third order Jerk chaotic system,the sliding mode controller is used for balance control.Linear sliding surface and exponential reaching law are used in the design of sliding mode controller.The hyperbolic tangent function is used instead of the sign function to weaken the eff ect of chattering.The simulation experiment system is built by using Simulink software,the sliding mode controller can balance the chaotic system.The simulation experiment is helpful for students to understand the theory of system simulation,chaos control and sliding mode control and to apply it in engineering.
