| Abstract |
This paper presents a general solution to the problem of tracking spatial saliencics for the estimation of flux, position and velocity in ac machines. Specifically a machine model is presented which accurately models the behavior of ac machines with multiple spatial harmonics. The effects that these multiple spatial hannonics have on flux, position, and velocity estimation is analyzcd, and methods arc presented utilizing multiple spatial harmonics to provide wide bandwidth estimates of flux, rotor position, and velocity. |
