Sampled Data High Gain Observer Design Combined with State Predictor For Synchronous PMSMs

• This work presents observer with sampled data measurements and his application to a surface permanent magnet synchronous motor. • The design of nonlinear observers with sampled measurements has received a great attention. • This interest is motivated by many applications such as Networks Communication Systems. • Recently, a hybrid samples data observer dedicated of a class of nonlinear systems has been presented. • This approach is based on an inter-sample time predictor, which estimates the output between two sampling instants. • The advantage of this algorithm is in the fact that the state estimates remain continuous time model. • At each sampling instant, the predictor is reset to the actual output .
