简要分析了影响稳瞄系统稳定精度的因素以及系统的性能需求。针对经典PID控制算法在该系统上存在的缺点和不足,设计了一种基于量化因子和决策因子自修正的模糊PID控制器,利用子模糊系统自适应调整量化因子和决策因子。实验结果表明,该方法克服了经典控制算法存在的不足,能有效地隔离载体扰动,系统的稳定精度和动态性能都得到了显著提高。
This paper briefly analyzes the factors that affect the stability of the stabilized system and the performance requirements of the system. Aiming at the shortcomings and deficiencies of the classical PID control algorithm in this system, a fuzzy PID controller based on quantization and self-tuning of decision-making factors was designed. The sub-fuzzy system was used to adaptively adjust the quantization and decision-making factors. Experimental results show that this method overcomes the shortcomings of the classical control algorithm, can effectively isolate the carrier disturbance, the stability and dynamic performance of the system have been significantly improved.
