Abstract. Electro-Mechanical Brake (EMB) is expected to be one of the future brake system. Feedback controller with sensor measuring is commonly used for control of EMB. However, this controller has some issues like delayed response and extra cost about sensor installation. In this paper, Feed-forward controller in EMB is proposed for solving these problems of feedback control. Also, it is very necessary to describe dynamical phenomenon of friction in actual EMB system. The actual EMB system shows stick-slip friction of mechanical parts which is difficult to model and apply to design of controller. This research is focused on exquisitely describing this stick-slip friction. In order to do this, the experiment about EMB is proceeded in the open loop system with the motor current command and data from the experiment is used for identification of model parameters during stiction. Then, parameters during slip is estimated in the closed loop system. Finally, developed friction model of EMB is proposed and it is utilized for design of feed-forward controller. Matlab Simulink is used for design of EMB simulation model and EMB test bench is utilized for experiment. Performance of proposed control system is compared with that of feedback control system.

A model of the EMB system is built, the main algorithm to control the EMB actor is completely the tripleloop PI control method, including current-loop, velocity-loop and pressure-loop. The determination of PI parameters is using Bode plots. Then, the software MATLAB is used to analysis on its pressure change in typical working conditions. The result contrast of the simulation and the hardware-inloop test shows the EMB system can well follow the target brake pressure and the overshoot of the brake pressure is controlled in the requirements range.

A dc motor based brake-by-wire system is studied for the purpose of fault diagnostics of its power electronic switches. The voltages and currents generated in the switching circuit under normal and faulted conditions are fed to a fuzzy algorithm to detect the particular solid state power switch which is faulty, and the moment of the occurrence of the fault. The algorithm can be easily implemented using an inexpensive processor for on-board diagnostics applications.
