Remote actuation systems and methods

An actuation system comprising:

• a motor;
• a sensing arrangement to provide measurement data indicative of a current position of the motor;
• power conversion circuitry coupled to the motor;
• an interface to receive an analog input command signal;
• an analog motor drive hardware coupled to the interface to convert the analog input command signal to an output indicative of a rotational speed command in a commanded rotational direction based at least in part on a relationship between a current state of a signal characteristic of the analog input command signal and a reference state for the signal characteristic;
• and
• excitation logic coupled to the analog motor drive hardware to convert the output of the analog motor drive hardware into one or more power conversion commands for operating the power conversion circuitry based at least in part on the current position of the motor.

An aircraft system comprising:

• a flight control component actuatable to influence at least one of a position and an attitude of an aircraft;
• an electrical cable;
• a flight control module coupled to the electrical cable to determine an actuation command for adjusting the at least one of the position and the attitude of the aircraft and transmit an analog command signal having a signal characteristic indicative of the actuation command;
• and
• an actuation system coupled to the electrical cable to receive the analog command signal, wherein the actuation system comprises:
• a motor coupled to the flight control component to actuate the flight control component;
• power conversion circuitry coupled to the motor;
• and
• one or more hardware modules coupled between the electrical cable and the power conversion circuitry, wherein the one or more hardware modules are configured to convert the analog command signal to one or more power conversion commands corresponding to a commanded rotational speed for the motor in a commanded rotational direction for the motor based at least in part on a relationship between a current state of the signal characteristic of the analog command signal and a reference state for the signal characteristic of the analog command signal and operate the power conversion circuitry in accordance with the one or more power conversion commands.
