Research On The Auto-Door Control System

Along with the unceasing development of modernized industry, the servosystem is widespread in many systems' applications day by day, the higher performance of the servo system is required. Permanent Magnet DC motor Servosystem can achieve the performances of high accuracy, fast response, large-scale speed and position servocontrol , therefore, the research on Permanent Magnet DC motor Servosystem turn into the most important one in the study of DC motor servosystem.The paper will research the Auto- Door DC Servo Driver,including four parts:1. Describe the maths model and control theory of Permanent Magnet DC motor, then it introduce the methods of timing and control system of PWM(pules width modulation).2.. In this part, it first describe the application otential and the basic component of the auto -door control system, and describe the hard ware designs.It introduces the basic function and features of AT89C52 and HIP4080AIP,and the harewares,including control power department, driving circuit, power-costing circuit and protection part It also design digital feed-back circuit.3. This paper describes realization software of the servosystem detaily.Inchiding: the design of the regulator, the control strategy and the realization; implement of roter inhializtion position to AT89C52, and so on In the whole process of software designing,the control of power is the key and difficulties.4. On the base of design of software and hardware, it describes the problems encountered in the debug and its solution. The experiment prove the system can be satisfy with the request of servo system, there are important signification for the design of servocontrol system and establish deep foundation for later research..
