Gain-Scheduled Yaw Control for Aircraft Ground Taxiing

Abstract a gain scheduled yaw controller is proposed to control low speed rolling and manoeuvring of an aircraft on ground. This method is based on local linearisation of a nonlinear model and the synthesis of a family of local controllers. A parallel feedforward action is added to achieve the setpoint tracking and let the feedback controller perform the regulation task. Simulation results show attractive and robust performances regard to the adopted control method.

Anti-Lock Braking System Using Predictive Control and On-Line Tire/Road Characteristics Estimation

A model predictive controller for optimal braking of a road vehicle is proposed. Taking into account the additional information provided by a torque sensor located in the wheel, there is no need to use any longitudinal model of the vehicle. Instead, we detail a way to identify a tire/road characteristic. This on-line reconstruction is based on an estimation of the longitudinal wheel slip and an estimation of the adhesion torque. The design approach, focused on the angular dynamics of the wheel, allows the use of the controller in vehicles for which assumptions on the longitudinal dynamics are not possible. Therefore, this controller is very indicated for aircraft applications.
