Mine-use Electrical Wheels Autonomous Dump Truck is the deal conveyance tool in the mine mountain of ten million ton per year and the construct engineering of large water with the high efficiency, the great carrying capacity and the good economy.This paper studies the drive and control of Autonomous Dump Truck which is with the high performance microprocessor as the core. It utilizes the vector control theory. Specially, the project develops a new kind of EV drive and control system. Main research achievement is as fellows:The vector control theory and its decoupling are introduced on the foundation of the mathematical model of asynchronous motor The variables in 2-Phase static coordinates are converted into the variables in rotating coordinates and the components between torque and magnetic field of stator winding current are decoupled which uses the rotor-field-oriented technology. thus, the speed regulating performance of the asynchronous motor is improved highly. The structure diagram of vector control system which combines the current model of motor is given and provides the theoretical basis for the design of vector control system platform.The thesis also introduce calculation of drive and power of induction motor based on the factual requirement of Mine-use Electrical Wheels Autonomous Dump Truck control, different speed gears and accelerator input are realized. Intimation system is established in the environment of MATLAB to validate these control arithmetic.A 22kw squirrel-cage IM is used to verify our method and a system of FOC control is designed. The system is made up of circuit cored around DSP(LF2407A) and circuit cored around IPM,By experimentation,the system has proved its good anti-jamming Performance and validates credibility of the system.By research of the driving system of Mine-use Electrical Wheels Autonomous Dump Truck the thesis combine the technology of FOC and DSP Perfectly ,a full digital FOC system is realized. the system proved its Enormous Practical value of application.
