摘要: 针对链式回转弹仓的精确定位控制问题,提出了一种带有积分型滑模面的自适应鲁棒控制算法。在常规自适应鲁棒控制的基础上引入积分型滑模面,减小了稳态位置误差;采用非线性鲁棒反馈增益代替常规的定常鲁棒反馈增益,改善了系统的动态性能;理论上证明了文中提出的控制算法具有更好的动态性能以及稳态性能。空载、半载和满载3种情况下的仿真结果表明,文中提出的控制算法对系统参数变化和外部扰动不敏感,与常规自适应鲁棒控制相比,具有更高的控制精度以及更好的控制性能。

Abstract: An adaptive robust control scheme with integral sliding surface is proposed for the precision position control of the rotational chain shell magazine. The integral operation sliding surface is embedded into the traditional adaptive robust control, and the steady state position tracking error is reduced. Constant robust feedback gain is replaced by nonlinear robust feedback gain, and the transient performance is improved. Mathematical analysis shows that the proposed control scheme can achieve better transient performance and has smaller steady state position tracking error. Simulation results in three conditions (empty-loading, half-loading and full-loading) show that the proposed control scheme is insensitive to parameter variations and external disturbance. Compared with the traditional adaptive robust control scheme, the proposed control scheme has higher position precision and better control performance.
