Title:
【発明の名称】速度調整のための加速度制御システム
Document Type and Number:
Japanese Patent JP2002532657
Kind Code:
A
Abstract:
In one embodiment, the present invention is a method for governing the speed of a device that involves generating a command signal based on a desired change in acceleration, the inertia of the device, and a load associated with the device. The command signal is output to actuating means for changing the acceleration of the device. A speed sensor provides a signal indicative of the speed of the device such as an engine, a movable machine, or a movable component of a machine. An error signal based on the difference between the actual speed of the device and the desired speed of the device is calculated. The desired change in acceleration is computed based on the error signal and a gain factor that is proportional to a desired response time of the control system. The desired change in acceleration is multiplied by an inertial gain factor that is derived from a previous command signal and the change in the speed of the device that resulted from a previous command signal. The inertial gain factor is computed and updated at selected intervals to account for changes in the inertia and load.
