Robust H-infinity Tracing Control of 3-DOF Helicopter Model
The stability and anti-jamming of 3-DOF helicopter model system are weak because of non-linearity and parameter uncertainty, so H∞ mixed sensitivity laws are adopted to design trajectory tracking controller. Firstly, the bounded non-linear parameters are transformed into the uncertainty of parameters and added by inherent parameters perturbation it composes the linear uncertainty model. The H∞ control method based on mixed sensitivity is adopted. By setting the weighting function of sensitivity and complementary sensitivity, the multitask controller of disturbance rejection and robust tracking is translated to a stander H∞ controller of regulate problem. Simulation results demonstrate that the trajectory of helicopter attitude tracks well and system robust stability is improved.
