Linear electromechanical actuator with sensorless position control

 Project in collaboration with a foreign industrial partner

Project description

A linear electromechanical actuator is designed, capable of satisfying a desired profile of the mover position in function of time. The LAI developed its own optimization method in which the optimization constraints are critical points of the function position(time). The mover position is estimated by superposing an additional (scan) voltage to the main voltage used to power the coil, in order to achieve the sensorless position control.
