Application of internal model control to sensorless force control on surfaces

In this paper, we propose an internal model control (IMC) system applied for sensorless force control on surfaces. This method is expected to be used for surface-polishing, deburring and rubbing machines. The IMC based controller has properties of disturbance decoupling, tracking performance and disturbance estimation. The previous paper introduced an IMC scheme for sensorless force control. In this paper, we present an extended IMC system and discuss the stability of its closed-loop system. Also, we verify the effectiveness of this system through experiments.
