Abstract: According to the problem of the waveform distortion with nonlinear load and poor dynamic response of the
EPS(Emergency Power Supply), by analysing the transfer function under different conditions with different load, a
compound control strategy combining the self-tuning fuzzy-PI control and the structure of triple closed loops is
proposed. Through the system simulation, this compound control strategy is tested on the 1 kW EPS. The experimental
results show that this control strategy has a good dynamic response, and a strong harmonic restrain ability.

Key words: digital signal processing(DSP), triple closed loops control, nonlinear load, emergency power supply, self-tuning fuzzy-PI
