英文摘要：

The design principle of predictive control is introduced and the predictive control algorithm design is also introduced. A multi characteristic power source which based on the core of TMS320LF2407A is developed by general PID-control integrated with predictive control. Experimental results show that the integrative control algorithm has good control characteristic and precede the general PID-control on the power source system. The power source is stable and the frequency ＆ amplitude of output waveform are variable as desire.
