Optimal Excitation Controller Design of Synchronous Generator Based on DSP

An optimal excitation controller based on the theory of linear optimal control is designed. TMS320LF2407 is used as its core unit. Taking advantage of the features of DSP such as high performance processing capabilities, plenty of peripherals on chip and high real-time control, man functions are realized such as rapid AC sampling, PID control algorithm, digital phase-shifted triggering and etc. The operating results show that the controller has higher control accuracy and better stability.
