Research on Multi Model LQR Control Method of Three DOF Helicopter

For the Three DOF helicopter model, to achieve fast and accurate tracking control, in the existing linear two type (Linear QuadraticRegulafor, LQR optimal control theory based on the multi model switching control, a multiple model, design model of LQR controller, select the most close to the current state of the model and its corresponding the role of the volume control on the helicopter model. MATLAB simulation and physical control results show that the control response time is shortened and the tracking error is reduced, which shows that the method is effective and can improve the rapidity and accuracy of tracking control.
