INCREMENTAL PREDICTIVE COMMAND OF VELOCITY TO BE GAINED GUIDANCE METHOD

In this paper a new incremental predictive guidance method based on implicit form of velocity to be gained algorithm is proposed In this approach the generalized incremental predictive control GIPC approach is applied to the linearized model to compensate for the guidance error Instead of using the present state in popular model based predictive controller MPC in the new method both previous and present states are utilized GIPC approach introduces a feedback action including the weighted di erence of the process states and the summation of the control action increments To evaluate the robustness and performance of the proposed approach the parameter uncertainties of the guidance and control are considered and a comparison with standard GPC is performed by extensive computer simulations The results show a signi cant improvement in the robustness as well as tracking performance of the perturbed initial value of velocity to be gained or the reference signal
