The Adaptive Control of Electric Pitch Servo System

The characteristics of electric pitch servo system are multivariable, nonlinear. In this paper, adaptive control method is used to satisfy the performance of rapid response, anti-interference and the location fast response non-overshoot. Neural networks model reference adaptive control is used in the speed loop to enhance the anti-interference performance and robustness. Fuzzy adaptive control is used in the position loop to satisfy the performance requirements of fast response and non-overshoot. The simulation results show that the adaptive control not only ensures strong anti-interference performance and robustness, but also achieve rapid response and non-overshoot exact location.
