Abstract
- Aiming at the problem of resonance of the platform of the motion control with high frequency and fast response driven by linear motor, research on the servo control system model, the model of the servo dynamic stiffnees, quality of moving parts, online identification algorithm and resonance suppre esion method of integral resonant control (IRC), a control scheme based on online identification model of recursive least squares identification algorithm and resonance suppression of IRC was proposed. The servo control system model and the model of the servo dynamic stüfness were constructed, based on the simulation, the platform of the motion control with high frequency and fast response driven by linear motor was studied considering the influence of quality change of moving parts on the servo dynamic stiifnes and the influence of the servo dynamic stiffnees of the control system on the resonance, IRC was designed to supprees resonance on the base of utilizing parameters of resonance model from online identification. The results indicate that the control scheme has a good rffect on suppreesing resonance which is caused by insufficient of the servo dynamic stiifness, and can greatly improve the dynamic performance of system.
