[Abstract]:In recent years, with the rapid development of domestic logistics industry, the application of electric forklift is more and more extensive. Electric forklift has the advantages of low pollution, low noise, high energy utilization rate and so on. These make electric forklift meet the theme of saving energy, low carbon and protecting environment. PMSMM has simple structure, high overload ability and high reliability. According to the characteristics of the drive system of electric forklift, this paper studies the servo drive control system of electric forklift based on permanent magnet synchronous motor (PMSM). This paper analyzes the basic structure and working principle of permanent magnet synchronous motor (PMSM). At the same time, the mathematical models of PMSM in different coordinate systems are obtained. The vector control method of PMSM is studied. The requirements of AC drive system for electric forklift are analyzed. The hardware circuit of PMSM control system is designed, which includes the main circuit of drive system, control circuit and protection circuit. The inverter circuit is controlled by SVPWM. At the same time, the related software control is designed. There are main programs and subroutines of each module. Finally, the simulation model of PMSM speed regulation system is built, and the immune single neuron PID control is used in the control algorithm. Through the comparison of simulation graphics, the immune single neuron PID control has faster response speed and shorter adjustment time than the conventional PID control. It improves the stability, robustness and rapidity of the control system. The electric forklift drive system studied in this paper is based on DSPTMS320F2812 chip as the main controller. For the electric forklift power supply, a special power module is designed. This module adopts a new type of DC-AC-DC converter, and improves the energy efficiency, battery efficiency and life cycle of the system. The immune single neuron PID control algorithm is used in this paper. The control effect of the system is greatly improved.
