Abstract
A control system may include: a motor configured to power a driven object; and circuitry configured to: generate a first driving force command to drive the motor during a first control; estimate a first force acting on the motor during the first control based, at least in part, on the first driving force command; generate a second driving force command to drive the motor during a second control after the first control; estimate a second force acting on the motor during the second control based, at least in part, on the second driving force command; and estimate an external force acting on the driven object during the second control based, at least in part, on a comparison between the first force and the second force.
