摘要
基于反步设计思想提出一种终端滑模控制方法,通过对混沌系统进行状态的变换,构造出快速收敛且收敛时间可以估计和计算的控制器,使得存在外部干扰的混沌系统输出能够在有限时间内跟踪上n阶可微的期望信号,保证系统的跟踪误差收敛至平衡点。并以Genesio为例进行了系统仿真。结果表明,该终端滑模控制器不仅具有良好的性能,而且具有较强的鲁棒性。
A terminal sliding mode control based on backstepping was proposed. Control is implemented through state transformation, and convergence time can be estimated, so that the chaotic system output can track the expected signal. The error variable can reach the sliding mode manifold. Genesio system is used to demonstrate the obtained results. The results show that the controller possesses the advantage of fast response and robustness.
