The aim of the presented paper is to introduce the reader to hardware-in-the-loop (HIL) simulation in electric drives, the motivation for its usage and its benefits. Basic information about HIL simulation in general and the connection to electric drives is followed by an explanation of the main principle of the dynamic emulation of mechanical loads for electric drives, which is a special case of HIL...
This paper presents the design of Unscented Kalman Filter (UKF) for estimation of state space variables of permanent magnet synchronous machine (PMSM). The UKF is shown together with the field oriented speed control. At first, the position and the speed of PMSM are measured, and UKF is used only for a load torque estimation. It is indicated how differences in sampling time of the speed and the current...
This paper presents a finite control set model predictive control strategy for the speed control of brushed permanent magnet DC machine. Main objective is to introduce and compare basic cost functions regarding speed control. Full order Kalman filter is used for the observation of the non-measured load torque and reduction of speed measurement noise. Influence of the proposed cost functions on the...
