Research of Modeling and Sliding Mode Advanced Control for Four Rotor Aircraft

In the process of the design of the four rotor, control system design is a crucial link. The real thing shows a certain or strong nonlinearity. By using the classical method, the control object is simplified to the linear and small perturbation model, and then we control the small perturbation model. However, the non-linear model is controlled directly in many advanced control theories. Advanced control theory can get rid of the traditional classical control modeling of imperfection. Variable structure sliding mode adaptive control system, is a kind of advanced controller, can use the switch sliding surface makes the system achieve good stability. This article first to the four rotor model, and then designed based on sliding mode control method, and has carried on the simulation research, proved the effectiveness of the method.
