Abstract
A method of using algorithmic control to operate and protect an actuator. The first control strategy uses a soft stop control method where an actuator is driven toward a stop. The actuator control system senses when the actuator is nearing the stop. A control strategy is implemented where the actuator movement is dampened prior to reaching the stop so that the actuator does not strike the stop abruptly. Another control strategy of the present invention involves using the actuator control system to monitor and calculate the integral value of the electrical current flowing though the actuator to determine if the actuator is operating beyond on its suggested operating range. This strategy will help to maximize actuator operation while preventing damage due to overheating.
