Abstract:
1. A method for performing user controllable autotuning of a Proportional-Integral-Derivative (PID) controller, the method comprising: displaying at least one graphical user input (GUI) element for specifying a desired performance characteristic of a PID controller autotuning algorithm; receiving user input to the at least one GUI element, wherein the user input comprises a user-drawn step response curve, wherein the user-drawn step response curve indicates the desired performance characteristic of the PID controller autotuning algorithm; deriving one or more parameter values indicating the desired performance characteristic of the PID controller autotuning algorithm from the user-drawn response curve; configuring the PID controller autotuning algorithm, wherein said configuring the PID controller autotuning algorithm comprises applying the one or more parameter values to parameters of the PID controller autotuning algorithm, wherein said configuring produces a configured PID controller autotuning algorithm; and executing the configured PID controller autotuning algorithm to tune the PID controller; wherein the user input indicating the desired performance characteristic indicates a desired operation of the PID controller after execution of the autotuning algorithm, and wherein the desired operation includes one or more of stiffness and response time.
