摘要
结合变稳直升机模拟它机的任务需求,探究了其变稳控制原理,深入分析了从开环模型跟踪到闭环模型跟踪的数学原理.根据原型机不同特性,提出了模型跟踪控制的一般步骤,并在MATLAB/Simulink中进行了仿真验证.结果表明,变稳直升机可跟踪的状态变量数目与操纵面数目一致,且稳定性不足时会导致跟踪误差发散.因此,在模型跟踪控制中,需选择主要跟踪变量,并引入状态反馈抑制跟踪误差发散.
Abstract
Based on the task requirements of simulating other aircraft with variable stability helicopters,the principle of variable stability control was explored,and the mathematical principles of tracking from open-loop model to closed-loop model were analyzed in depth.General steps for model tracking control were proposed based on the different characteristics of the prototype,and simulation verification was conducted in MATLAB/Simulink.The results indicate that the number of state variables that a variable stability helicopter can track is consistent with the number of control surfaces,and its insufficient stability can lead to divergence of tracking errors.Therefore,when conducting model tracking control,it is necessary to select the main tracking variables and introduce state feedback to suppress tracking error divergence.
