【摘要】：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。
[Abstract]:Laser sensor tracker is easy to be affected by small disturbance in signal modulation identification, which leads to signal instability, so signal stability control is needed. In order to improve the signal control stability of laser sensor tracker. A method of signal stability control for laser sensor tracker based on linearized small disturbance error compensation and PID self-tuning qualitative parameter adjustment is proposed. Firstly, the three-channel tracking signal transmission pattern under small disturbance of laser sensor is established. Equation of state. The stability of the signal tracking controller is analyzed and the linearized small disturbance error compensation control is carried out under the condition of uncertain factors. Then the self-tuning qualitative adjustment method of PID is used to realize the adaptive fusion of laser sensor output signal to improve the stability of the signal tracking and identification process. Finally, the simulation test results show that. Using this method to control the signal stability of laser sensor tracker, the error caused by small disturbance can be minimized, and the precision of laser sensor tracker to target location and tracking can be improved.
