In this paper, modelling, control and position estimation for a linear electromagnetic actuator with a permanent magnet mover is presented. A hybrid methodology combining analytical and Finite Element Method (FEM) is adopted for modelling of the actuator. An online parameter estimation method is presented for estimating the electrical parameters based on current switching instant sampling. Two controllers are implemented: the Linear Quadratic Regulator (LQR) and the Proximate Time Optimal Servo Controller (PTOS). Position estimation is realized through the Luenberger Observer.
