摘要
利用滑膜控制算法(SMC)控制PMSM具有鲁棒性强,响应速度快等优点。但由于滑膜控制本身存在抖动现象,单纯的使用滑膜控制算法控制电机会因为抖振影响到系统的稳定性。而模糊控制在处理不确定信息方面较强,并且模糊模糊控制的设计不依赖对象的精确数学模型。本文在滑膜控制PMSM的基础上融合模糊切换增益调节,设计模糊规则,并根据滑模到达条件对切换增益进行有效估计,使系统滑模控制中的切换增益可自适应逼近,利用切换增益消除干扰项。最后在MATLAB/Simulink仿真平台验证了该控制方法确实有效消除滑膜控制带来的抖振。
Using the slip film control algorithm(SMC)to control PMSM has the advantages of strong robustness and fast response.However,due to the existence of jitter in the synovial control itself,simply using the synovial control algorithm to control the motor will affect the stability of the system due to chattering.Fuzzy control is more powerful in dealing with uncertain information,and the design of fuzzy fuzzy control does not depend on the accurate mathematical model of the object.Based on the synovial control PMSM,the fuzzy switching gain adjustment is combined,the fuzzy rule is designed,and the switching gain is estimated effectively according to the sliding mode arrival condition,so that the switching gain in the system sliding mode control can be adaptively approximated,and the switching gain can be eliminated.Disturbing term.Finally,the MATLAB/Simulink simulation platform verifies that the control method effectively eliminates chattering caused by slip film control.
