Analysis and Simulation Research on the Principle of Helicopter Model Following Variable Stability Control
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.
