This paper presents a general design approach for a performance based tuning of a damping injection framework impedance controller by using insights from PID motion control tuning rules. The damping injection framework impedance controller is suitable for human friendly robots as it enhances safety due to the compliance it introduces and guarantees asymptotic stability because of its passive nature. In order to perform successful manipulation with a damping injection framework controlled robot, a performance based analysis and tuning of the controller is essential. By mapping a performance based frequency domain tuning of PID controllers on the framework, the proposed tuning method attempts to analyze and define controller parameters that yield a desired performance requirement given in terms of the maximum allowed position error. The effectiveness of the proposed guideline is illustrated with simulation and experimental results.
