Drive control method and drive controller
First Claim

1. A drive controller comprising:
- a control means configured to detect a position of a driven element and to perform feedback control to cause the driven element to move by a driver based on a position command and the detected position;
a collision detecting means configured to detect a collision of the driven element; and
a collision processing means, wherein the control means controls the driven element by the driver to cause the driven element to continue its current movement, in addition to the feedback control of the movement, the collision detecting means detects the collision of the driven element based on an estimated speed deviation which is an estimated deviation from an actual speed of the driven element or an estimated acceleration deviation which is an estimated deviation from an actual acceleration of the driven element, and the collision processing means causes the driven element to reverse a movement before the collision after causing the driven element to stop continuation of the current movement by the control means, based on a signal indicating that a collision has been detected.

Abstract
A drive controller (10′) of the present invention comprises control means (28, 29, 32 to 38) configured to perform control to cause a driven element to move by a driver (M) and a collision detecting means (20) configured to detect a collision of the driven element. The collision detecting means detects the collision of the driven element based on an estimated speed deviation which is an estimated deviation from an actual speed of the driven element or an estimated acceleration deviation which is an estimated deviation from an actual acceleration of the driven element.

10. A drive control method comprising the steps of:
-
performing feedback control by detecting a position of a driven element and by causing the driven element to move by a driver based on a position command and the detected position;
detecting a collision of the driven element; and
processing the collision, wherein in the step of performing control, the driven element is controlled by the driver to cause the driven element to continue its current movement, in addition to the feedback control, in the step of detecting the collision, the collision of the driven element is detected based on an estimated speed deviation which is an estimated deviation from an actual speed of the driven element or an estimated acceleration deviation which is an estimated deviation from an actual acceleration of the driven element, and in the step of processing the collision, the driven element is caused to reverse a movement before collision after causing the driven element to stop continuation of the current movement in the control step, based on a signal indicating that a collision has been detected. - View Dependent Claims (11, 12, 13, 15, 17, 18)
