【学会优博】王树波:非线性伺服系统干扰补偿及自适应控制研究
一、论文主要内容及创新点
针对伺服系统广泛存在的摩擦、非线性动态、参数不确定性、外部扰动以及参数未知造成的控制困难问题,以提高伺服系统的控制精度为目标,研究了伺服系统的干扰补偿、振动抑制、参数估计和自适应控制器设计。并通过伺服系统试验平台验证了本文所提控制算法的有效性。
1)针对伺服系统的瞬态性能难以事先设计问题,提出了自适应指定性能控制器设计方法;
2)针对二惯量伺服系统存在机械振动,提出了自适应神经网络扭矩振动控制策略;
3)针对伺服系统的参数未知,提出了基于参数误差信息的有限时间参数自适应估计方法;
4)针对伺服系统难以实现渐近稳定问题,提出了鲁棒自适应渐近跟踪控制策略。
