HIGH-INTEGRITY ACTUATOR CONTROLLER AND CONTROL SYSTEMS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240305224 titled 'HIGH-INTEGRITY ACTUATOR CONTROLLER AND CONTROL SYSTEMS

The abstract describes a high-integrity electromechanical actuator control system consisting of a system function controller, multiple actuator controllers, and at least one electromechanical actuator. Each actuator controller includes a primary channel with a first controller, a second controller, and a duty cycle computation circuit, as well as a backup channel with a backup controller. The first and second controllers receive digital actuator control commands from functional control channels and generate duty cycle commands, while the duty cycle computation circuit computes an average of these commands to produce pulse width modulated (PWM) commutation control signals. The backup controller receives digital actuator control commands from different functional control channels and generates backup PWM commutation control signals.
