Design Of Electric Forklift Controller Based On CAN

As the developing of human society,environment problems are increasingly drawing people's attention. As an environmental-protection vehicle,electric forklift plays an important role in field of modern material distribution,for its good maneuver ability and reliability.In this paper,the design of electric forklift driving controller is demonstrated. Otherwise,CAN is added into this controller,so as to build up CAN networks with other modules equipped with CAN controllers.This paper is composed of 7 chapters:in the first chapter,the background of the paper is introduced;in the second chapter,the structure of electric forklift is demonstrated;in the third chapter,first the math model of series motor is found,then the motor is controlled as improved P1D control rule;in the fourth chapter,the principle and realization method of forward and reverse rotation and back-feed brake are explained;in the fifth chapter,the principle of CAN and design of application layer in CAN are illuminated;in the sixth chapter,the principle of E2PROM is clarified;in the last chapter,summary of the whole paper is given,and prospect in this field is made.
