Through experimental analysis, the design uses DSP and Intelligent Power Module (IPM) bination of control system for elevator door operation by setting curve and stable operation. Keywords： Permanent mag linear synchronous motor。Elevator Door Machine。mainly include controller,SPWM,signal generator,rectifier circuit,intelligent power module IPM and sensors, etc. The controller selects and uses the TI Company’s TMS320LF2407, 2407 has builtin module and pulse coding capture circuit, which can produce PWM power module IPM uses Fuji Company’s 6MBP15RH060,to simplify the power circuit design by the builtin drive system’s designation is mainly revolves control chip 2407 and intelligent power module IPM, using hall current sensor monitoring electric current on realtime, the current signal sent to DSP control chip to current peculiar protection.[2][3] Adopting photoelectric encoder detecting the door’s operating position and speed. Figure 2 control system handware structure C. System controller chart The control system use feedback control on three close loops: the position P,velocity V,and current I, diagram of system controller block as shown in Figure 3. The control process is,first of all, pare location P measured by optical encoder and position mand P*,then find the speed mand value V* by the position controller,the signal by pared V with V* after the speed controller find the current vector mand I。 the main function is to plete the door and control of operating parameters of the modified door operation by setting features such as running speed curve. Main program includes system initialization and main loop body position. Initialization includes initialization of the DSP and the external devices. Initialization is plete, enter the main loop, the system is running under the control of parameters set. [6]Door width
