A Sensorless Method for Detecting Spool Position in Solenoid Actuators

A method is developed to estimate the position of the moving part in a solenoid actuator. We superpose a sinusoidal component onto the base duty ratio of the drive PWM (Pulse Width Modulation), thus, a scan signal is generated which is used to first identify, then to “measure” the system during...
