A space based vehicle includes a controller configured to generate a pulse width modulation (PWM) control signal and output the PWM control signal at a control signal output. A self-correcting frequency controlled current limiter is connected to the control signal output. The self-correcting frequency current limiter provides a current limited control signal output and a buffered feedback loop output connected to a feedback input of the controller. A direct current (DC) motor includes a control input connected to the current limited control signal output and an instantaneous input current sensor.
