摘要
首先定义滑模面函数为系统状态变量的运动轨迹,保证其沿着最优轨迹滑动。设计了相应的指数趋近率,使状态变量快速平稳趋近滑模面。180°、90°、60°阶跃输入信号仿真结果表明,系统输出响应上升时间均小于0.6s,调节时间均小于0.5s,超调量为0。
To guarantee the state variables of system moving along the best trajectory, slide surface function is established as the trajectory of the system variables. The exponential reaching law of algorithm is designed to get shorter time for the variables to reach the surface of sliding model. Simulation with step signal inputs such as 180°, 90°, 60° show that the overshoot is near zero with shorter than 0.6 s rising time and 0.5 s adjust time.
