Control Strategy Research And Controller Development For Electric Sprinkler

The design of the control strategy is one of the key technologies of electric vehicles. The economy and security of Electric vehicles are based on the control strategy. The control strategy judges the driver’s intent through devices which the driver controls, such as switches, pedals. The control strategy is designed to meet the driving needs as well as to achieve optimal distribution of energy and power output, to control battery system, motor system and other equipment to work coordinated. As an important part of the electric vehicle, the controller also acts as the the physical device which the control strategy is carried out. The design of control strategy and the controller have been paid high attention by automobile manufacturers. In this article, first of all, according to the usage requirement, we arrange the circuits in the electric sprinkler and the parameter matching of the sprinkler’s power system. Then, with the help of Cruise which is a soft developed by AVL, we finish the simulation and test. According the working condition of the electric sprinkler, we divided working modes and developed the model of the controller in the environment of dSPACE, which is a Real-time simulation system developed by a company named Vector. The model was tested by HILS(Hardware-in-the Loop Simulation) system.We finished the I/O chart which based on the model, identified the input signal and output signal of the controller. Then we designed the Communication model of the electric sprinkler which based on SAE J1939.Finished the PCB after choosing the right chips and designing the schematic. After finished the hardware, we wrote code. After bench test, the controller meet the actual needs of the electric sprinkler.
