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

This abstract first appeared for US patent application 18527667 titled 'HIGH-INTEGRITY ACTUATOR CONTROLLER AND CONTROL SYSTEMS

Simplified Explanation: This patent application describes a high-integrity electromechanical actuator control system that includes a system function controller, multiple actuator controllers, and at least one electromechanical actuator. Each actuator controller has 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 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 generate pulse width modulated commutation control signals. The backup controller also generates backup PWM commutation control signals.

Original Abstract Submitted

A high-integrity electromechanical actuator control system includes a system function controller, a plurality of actuator controllers, and at least one electromechanical actuator. Each actuator controller includes a primary channel having a first controller, a second controller, and a duty cycle computation circuit, and includes a backup channel having a backup controller. The first controller receives digital actuator control commands from two functional control channels and supplies first digital duty cycle commands. The second controller receives digital actuator control commands from two functional control channels and supplies second digital duty cycle commands. The duty cycle computation circuit computes an average of the first and second duty cycle commands and generates pulse width modulated (PWM) commutation control signals based on the computed average. The backup controller receives digital actuator control commands from two different functional control channels and generates and supplies backup PWM commutation control signals.
