Popis: This paper is focused on the angular velocity estimation for the electric machine drive system. The angle tracking observer with filtered control variable presented in this paper uses the angular position information for the velocity estimation. The angular position is given by the optical quadrature encoder. The angle tracking observer is composed from the PI controller, first order Butterworth filter and the integrator. A tuning approach for the PI controller and flter constants is presented in this paper as well. The presented approach is compared with the angle tracking observer without Buttherworth filter and with traditional velocity estimate by the simple diference. Experimental results are gained either by the simulation or by the experiment at the real device.
