摘要
将基于紧格式线性化的非线性系统无模型自适应控制方法应用于直线电机的运动控制中.用紧格式动态线性时变模型替代直线电机非线性系统模型,根据直线电机运动模型的输入输出数据在线估计系统的伪偏导数.仿真实验表明,紧格式无模型自适应控制方法对电机这种具有不确定动态的非线性系统有较强的自适应性、抗干扰性、稳定性和鲁棒性.
The model-free adaptive control (MFAC)approach of nonlinear systems based on linearization of strict format is applied to motion control of the linear motor.The strict format dynamic linear time-varying model is used to replace nonlinear system model of linear motor.Pseudo partial derivative is estimated online by the input and output data of motion model of linear motor.The simulation results show that tight format model-free controller has a strong adaptive,anti-interference,stable and robustness for motor with vaguely known dynamic nonlinear systems.
