Motor Angular Position Control - A simplified explanation of the abstract

This abstract first appeared for US patent application 18430178 titled 'Motor Angular Position Control

Simplified Explanation

The patent application describes a motor controller that controls the rotational speed of an output shaft of an electric motor using a proportional controller and a time-optimal controller.

• The proportional controller manages the rotational speed when the present rotational position is between a target rotational position and a switching point.
• The time-optimal controller manages the rotational speed when the present rotational position is not between the target rotational position and the switching point.
• The switching point is determined in a way that minimizes overshooting the target rotational position while maximizing the speed at which the target rotational position is reached.

Potential Applications

The technology can be applied in various industries such as robotics, automation, electric vehicles, and industrial machinery where precise control of rotational speed is required.

Problems Solved

1. Overshooting of the target rotational position is minimized, ensuring accurate control. 2. The time-optimal controller allows for efficient and quick reaching of the target rotational position.

Benefits

1. Improved precision in controlling rotational speed. 2. Enhanced efficiency in reaching the target rotational position. 3. Reduced wear and tear on the motor due to optimized control.

Potential Commercial Applications

Optimized motor controllers can be utilized in industries such as manufacturing, automotive, aerospace, and renewable energy for applications requiring precise speed control.

Original Abstract Submitted

A motor controller to control rotational speed of an output shaft of an electric motor. The motor controller includes a proportional controller and a time-optimal controller. The proportional controller controls the rotational speed when a present rotational position of the shaft is between a target rotational position and a switching point, inclusively. The time-optimal controller controls the rotational speed when the present rotational position is not between the target rotational position and the switching point. Also introduced herein are aspects pertaining to determining the switching point in a manner that minimizes overshooting the target rotational position while maximizing expediency at which the target rotational position is reached.
