Title
Switching operation mode resonance ratio control for flexible robot system
Abstract
Controlling robot with the mechanical resonance has been receiving increased attention. A new effective control method, a resonance ratio control, has been introduced as a new way to guarantee the robustness and suppress the oscillation during task executions for position and force control system. This work presents a new approach to the controlling of flexible robot system by a switching operation mode resonance ratio control. To calculate the optimal parameters of position/force servoing based on resonance ratio control, a Coefficient Diagram Method (CDM) is employed. In this paper, we introduce a novel approach that automatically adapt algorithm parameters conditional based on the operational tasks. Moreover, a multiencoder based disturbance observer (MEDOB) is shown to estimate the external force on the load side, rather than using a force sensor. The experiments with a linear motor and spring show the validity of the approach. From the experiments, it can reject vibration to improve controlling performance.
