摘　　要：平台调平控制是一个重要且复杂的过程,很难用一个精确的数学模型来描述,而传统的PID控制稳态精度不高、抗干扰性差,难以满足复杂环境下的自适应调平需求。因此,设计了模糊PID控制算法来对飞行器发射平台进行调平,介绍了模糊PID控制的设计方法,系统采用AMEsim和MATLAB/Simulink联合仿真,并将传统PID控制和模糊PID控制的仿真结果对比。仿真结果表明:模糊PID控制的平台调平相较于传统PID控制具有更高的控制精度和动态性能,调节速度提高了40%以上,无超调,无滞后,具有更好的抗干扰性和鲁棒性。使用AMEsim对平台调平系统建模,大大的提升了设计效率,在MATLAB中设计控制算法利用该软件强大的计算能力,使仿真的结果更加精确可靠。Platform leveling control is an important and complex process,it is difficult to describe with an accurate mathematical model.However,the traditional PID control has low steady-state accuracy and poor anti-interference performance,which is difficult to meet the requirements of adaptive leveling in complex environment.Therefore,the fuzzy PID control algorithm is designed to level the launch platform of aircraft.The design method of fuzzy PID control is introduced.The system is simulated by AMESim and MATLAB/Simulink,and the simulation results of traditional PID control and fuzzy PID control are compared.The simulation results show that:compared with the traditional PID control,the fuzzy PID control platform leveling has higher control accuracy and dynamic performance,the adjustment speed is increased by more than 40%,no overshoot,no lag,and has better antiinterference and robustness.AMESim is used to model the platform leveling system,which greatly improves the design efficiency.The control algorithm is designed in MATLAB,which makes the simulation results more accurate by using the powerful calculation ability of the software.
