Abstract:
A method for controlling an autonomous vehicle to repeatedly follow a same predetermined trajectory comprises: a) receiving a target trajectory signal indicative of the predetermined trajectory; b) generating a control signal adapted to steer the vehicle along the predetermined trajectory; and, for at least one of a number of iterations: c) steering the vehicle along the predetermined trajectory by feeding the control signal to the vehicle; d) measuring an actual trajectory followed by the vehicle in response to being steered according to the control signal; e) recording an actual trajectory signal indicative of the measured actual trajectory; f) using an iterative learning controller to determine an altered control signal using the control signal, the actual trajectory signal and the target trajectory signal. The method allows to improve a tracking performance during a subsequent iteration.
