激光传感跟踪器在信号调制识别中容易受到小扰动影响,导致信号失稳,需要进行信号稳定性控制。为了提高激光传感跟踪器信号控制稳定性,提出一种基于线性化小扰动误差补偿和PID自整定性参数调整的激光传感跟踪器信号稳定控制方法。首先建立激光传感器的小扰动下的三通道跟踪信号传输状态方程,设计信号跟踪控制器进行稳定性分析,在存在不确定因素条件下进行线性化小扰动误差补偿控制,然后采用PID自整定性调整方法实现激光传感输出信号的自适应融合,提高信号跟踪识别过程中的稳定性。最后进行仿真测试,结果表明,采用该方法进行激光传感跟踪器的信号稳定控制,能最大限度降低小扰动产生的误差,提高了激光传感跟踪器对目标定位跟踪的精度。
Laser-sensing tracker is susceptible to small disturbances in signal modulation recognition, resulting in signal instability and signal stability control. In order to improve the signal control stability of laser sensor tracker, a signal stability control method based on linearized small disturbance error compensation and PID self-tuning parameter adjustment is proposed. Firstly, the three-channel tracking signal transmission equation of state under the small disturbance of the laser sensor is established. The stability of the signal tracking controller is designed. Under the condition of uncertain factors, the linearized small disturbance error compensation control is implemented, and then PID self-tuning is adopted The method achieves adaptive fusion of the laser sensing output signals and improves the stability of the signal tracking and identification process. The simulation results show that the proposed method can stabilize the signal of the laser tracker and minimize the error caused by the small perturbation, and improve the accuracy of the laser tracker tracking the target.
