This paper puts forward a four-axis dual rotor unmanned aerial vehicle (UAV) and builds the mathematical model. For this model, an aircraft trajectory control method based on robust compensation is presented. To reduce the effects of external disturbances and model parameters' uncertainty, the robust compensator is added to the classical PD control. Simulation results demonstrate that this method...
In order to overcome the stochastic volatility and state of non-after-effect, we use the b-spline polishing method which have excellent properties of approximation, smoothness, convexity preserving and integrity to randomly optimize and modify weighted Markov model, and eventually corrected weighted Markov model by method of stochastic optimization burnishing. When the model is applied to prediction...
