[Abstract]:With the expansion of power network and the continuous improvement of generator capacity, the control performance and response speed of generator to excitation control system are higher and higher. The development of control theory and power electronics technology, It promotes the development of digital excitation control system. Combined with the improved particle swarm optimization algorithm, the excitation closed-loop control system based on TMS320F2812 and the CANopen communication network based on Visual C are designed. Firstly, the basic control principle of excitation control system, including the control process of excitation control system, is described in this paper. The third order mathematical model of excitation control system is established, and the realization of improved particle swarm optimization algorithm in excitation control system is studied deeply. The application of the improved Particle Swarm Optimization (PID) algorithm in excitation control system is verified by using Matlab, and the hardware composition of the upper and lower computer of the excitation control system is introduced in detail, including the application of the improved PSO algorithm to the excitation control system and the application of the improved PSO algorithm to the excitation control system by using Matlab. On the basis of establishing the hardware platform, the most critical program of the system is written and debugged and verified, including the main program of excitation control system, the interrupt program of analog sampling based on over-sampling algorithm, and the program of capturing interrupt. Three point forward data recording interrupt program, Finally, the communication protocol of excitation control system CANopen based on CAN bus is designed. The uplink and downlink data of communication network are debugged by eCAN module of DSP and API function of Visual C. And achieved good communication effect.
