摘要: 以某机器人为研究对象,使用S(Sigmoid)面控制方法构造了速度控制器并分析了该控制器的稳定性. 参考滑模变结构控制思想,提出了参数自适应S面速度控制器,使控制参数根据运动状态自适应调整. 同时,为了提高S面位置控制器的适应性,改进了控制器的自适应调整项,增强了控制器消除稳态误差的能力,实现了S面控制器局部动态调整. 水池中的对比实验和海洋验证实验表明,改进方法获得了良好的控制效果,有效提高了水下机器人运动控制的适应性.

Abstract: (Sigmoid) plane control method is an effective and simple method for the motion control of autonomous underwater vehicle (AUV). A velocity controller was constructed and analyzed by S plane control method. According to sliding mode controller (SMC), an integral S plane velocity controller with selfadapting integration step was proposed in order to make control parameters adjusted by motion state. Then a selfadapting item was improved for eliminating steadystate errors and adjusting dynamically S plane controller locally. Both pool and sea experiment results show that the improved controller is effective and the adaptability of AUV motion control is strengthened largely.
