摘要
研究了航空光电吊舱陀螺稳定系统的模糊PID控制.该系统对跟踪精度和响应速度要求高,传统的PID控制难以满足对性能指标的要求.而模糊PID控制可显著改善控制系统对高速动态目标的捕获跟踪能力.因此,将模糊PID应用于航空光电吊舱陀螺挖稳定系统,改善了控制系统的过渡过程、减小了超调量,又提高了系统跟踪精度、稳定精度和响应速度,增强系统的鲁棒性.用Matlab仿真验证了该方法的有效性.
Gyro stabilized sighting system demands higher accuracy and fast responding speed to track targets, but the conventional PID controllers cannot meet the demands. Instead, the fuzzy PID control can greatly improve the capturing and tracking capacities to high-speed dynamic targets. So we apply the fuzzy-PID controller in the positioning loop of the stabilized system, not only improving the transient process of the control system and decreasing the overshoot, but also enhancing the accuracy of tracking, stabilization and response. At the end, simulations were performed to test the effectiveness of this method through the Matlab platform.
