    摘要： A method for estimating the state of a system, as well as an extended Kalman filter (EKF), allows nonlinear mathematical models to be used for describing the system. Accurate precision is provided since the method is based on an EKF technique while using a filter that implements a first degree Stirling approximation formula. The method may be used for estimating position and speed of a brushless motor, and may be implemented in a relative device. Such a device may be introduced in a control loop of a brushless motor of a power steering system for a vehicle to provide a countering torque on the steering wheel based on speed of the vehicle and a steering angle of the vehicle.

    摘要： An embodiment of a control system of a braking device is provided. Said braking device includes at least one braking element adapted to apply a braking action to a moving body. The control system includes receiving means for receiving an indication of a target value of the braking action to be applied to the moving body, measuring means for measuring an indication of an actual value of the braking action applied to the moving body and driving means for driving the braking element according to a comparison between the target value and the actual value. The measuring means includes sensing means for sensing a warping of at least one part of the moving body and/or of the braking device, and logic means for estimating the actual value according to the warping.
