Three Variables Dynamically Synchronized Control for Double Position Drive with Linear Servo Motors

Guo Qingding Lan Yipeng(Shenyang University of Technology 110023 China)  
A new three variables dynamically synchronized control method for double position drive with linear servo motors is presented This paper shows the design of an H ∞ robust controller to be used both speed and acceleration state feedback control,which can rapidly restore synchronous state under he condition of unbalanced loads or random disturbances The dynamically synchronized control of acceleration,speed and position is achieved Two linear permanent magnet synchronous motors(LPMSM)with the same parameters are used as driving parts The results of simulation test indicate that the proposed system has strong robustness,and that the dynamical synchronous error is smaller during dynamic process
