基于DSP的电动叉车驱动控制系统硬件设计

Hardware Design of Electric Forklift Driving Controlling System base on DSP

主要研究电动叉车交流控制系统,以微处理器为核心,采用异步电动机直接转矩控制算法,设计基于TMS320F2812的电动叉车用交流驱动控制器。采用直接转矩的控制系统,该系统稳定且适宜于在电动工程车辆中推广应用。根据电动叉车的性能指标,采用空间电压矢量分析方法,分析了直接转矩控制的基本原理、结构和算法。针对该系统设计了DSP控制器,并设计了驱动器的外围电路。

This thesis has studied exchange control system of electric forklift, with the focus on microprocessor, utilizes thearithmetic of asynchronous electromotor direct torque control, and designs Ac drive controller which can he applied to TMS320F2812 electric forklift, the thesis also introduced that direct torque control system is stabilization and this system is fitting engineering vehicles. This system can be widely used in engineering vehicles. Analyzed the basic principles, struc- tures and algorithms of DTC by using the analyzing methodology of space voltage vector. With the aim at this system, designed the DSP controller and devised the driving periphery of the circuit, including circuit design.
