SPEED CONTROL SYSTEM

Title:

SPEED CONTROL SYSTEM

Document Type and Number:

WIPO Patent Application WO/1985/004534

Kind Code:

A1

Abstract:

A speed control system for a servo motor has means (1) which presumes speed (Vl) at the tip of the machine load as well as torque stress or resilient displacement (d) in the load transmitting system, based upon a speed signal (v) and a torque instruction signal (u). A feedback signal from said means (1) is added to the torque instruction in order to realize speed control with excellent response characteristics and stability, without providing a sensor that detects displacement in the machine load transmitting system or speed at the tip of the machine load.
