IPC: G05D3/00
Filed: 1989-05-31
Abstract: PURPOSE:To speed up the detection of collision by forming a model for a servo system and detecting the collision of a driven body driven by a servo motor with a foreign substance in accordance with a difference between a positional deviation obtained by the model and a positional deviation obtained by a real servo circuit so that the influence of acceleration is compensated. CONSTITUTION:The servo system model 14 for inputting a speed command Vc from the servo system 12 and consisting of transmission functions 16, 18 constituted of the gain K of a position control part setting up a transmission function obtained until the servo motor responds at a speed V to '1' and an integrator is formed. The positional deviation epsilonm found out by the model 14 is subtracted from the positional deviation epsilonc obtained by the real servo circuit by a subtractor 20, whether the absolute value of the subtracted value is larger than a set prescribed value or not is decided by a comparator 22, and when the absolute value is larger, a collision detecting signal is outputted. Consequently, the collision of the driven body driven by the servo motor with a foreign substance can be quickly detected.
