In recent years, with the high economic growth, the amount of high-rise buildings in the city is increasing rapidly. As the result of that, the demand of elevators is also increasing. This project is based on Jiangsu technology supporting project "Research on the new PMSM elevator drive and control system", researching the new elevator drive and control technology of PMSM elevator, while achieving the integration of elevator drive and control system. Through this project, the competitive ability of the domestic elevator market can be largely enhanced.A PMSM drive and control system based on the core chip of DSC28335and CPLD EPM3256is designed and developed independently in this project. The main part in this paper contains four tasks below:Firstly, based on DSC28335and CPLD EPM3256, the system is designed as the requirement of needs analysis and feasibility analysis of Elevator Drive and Control System. The DSC28335is mainly used to complete the loop current, torque and speed control. The EPM3256is mainly used to complete floor control of digital signal.Secondly, the whole hardware control system and driving system are designed in this paper based on the system analysis. The whole system is divided into many parts which contain core control module, hall sensor module, inverter module. PWM driving module, communication module, relay driver module, power management module, temperature detection module, fan control module, etc. The hardware circuit is optimized according to the theory of EMC by circuit simulation, which makes the hardware circuit system become more reliable, stable and lower power consumption.Thirdly, the software algorithms are designed with the actual condition of hardware system including parameter configuration of the chip, the algorithms of AD sample, angle position detection, SVPWM, etc.Fourthly, functional modules are tested with the elevator system in the simulation. The result shows that this elevator system possesses a stable and reliable control performance which meets the design requirement perfectly.
