| Abstract: | As a high-quality power source undertaking peak load and frequency regulation,hydropower stations play an important role in ensuring the safe and stable operation of the power grid,which expects a lot from the regulation performance of hydropower units.In order to improve the control quality of the hydro-turbine regulating system,based on the nonlinear model of hydro-turbine,a model-free adaptive control(MFAC)combined with discrete sliding mode approaching law control for hydropower unit regulation is proposed according to the dynamic linearization theory and Lipschitz condition.The parameter optimization of the controller of the hydropower unit is realized by using the beetle antennae search(BAS)combined with the error integral criterion function.The simulation results show that the MFAC sliding mode controller has advantages like small overshoot and short rise time compared with the optimal PID controller under different operating conditions.Meanwhile,the BAS algorithm has excellent parameter optimization effect,short calculation time and a good application prospect. |
