Optimizing brake-by-wire control

An optimal control strategy is introduced that ensures minimum control effort, resulting in minimum actuator power consumption while simultaneously providing efficient braking performance.

Over the past few years, research has been directed toward expanding development in the field of x-by-wire systems. This generic term means that the conventional mechanical and hydraulic connections between the commanded input and actuating subsystems are replaced with electrical wires carrying the operating electrical signals.

The first appearance of this concept was in the aviation field because of the high potential role it can play in reducing the space and weight allocated to the mechanical/hydraulic connections, in addition to boosting aircraft performance via more consistent and responsive communications between the different subsystems. After that, the ground-vehicle industry was motivated to implement this new technology for a variety of different vehicles.
