- Minimum variance lateral-directional control of a bank-to-turn missilePublication . Medroa, David Vicente; Bousson, KouamanaThe objective of this work is to project a minimal variance controller for a Bank-To-Turn (BTT) missile on the lateral-directional part of the flight. BTT is a way of turning the missile orienting the maximum of normal aerodynamic forces with the plane of the commanded direction using pitch and roll while maintaining a zero sideslip angle. In the first part of this work a brief history and state of the art are made, then the BTT navigation is briefly compared to others, then the BTT navigation is explained. After the introduction the Lyapunov stability is explained in both continuous and discrete, the H-infinity method is now presented then the minimum variance method is described, then the control law is presented, then the analysis is made using Matlab. The objective of the controller is to minimize the variance of the variance of the function or functions used in order to have a smother curve of points and therefore the control is easier, a comparison is made between the methods.
