ELEC 251 Lecture Notes - Lecture 1: Pid Controller, Proportional Control
Document Summary
The goal of manual tuning to have the tuning parameters set close to the optimum settings when the controller is initially installed. Setpoint step change method a manual tuning method that consists of making small changes in the setpoint and observing the responses. A series of controller tuning changes is made until the controller response is satisfactory. Setpoint step change method: if a derivative function is needed, set it to a value in minutes no larger than the integral time, if derivative is added, it may be necessary to reduce the proportional gain. Ziegler-nichols tuning methods open-loop and closed-loop methods that make changes to the process and measure process parameters related to how the system responds to the changes. Z-n methods are empirical and intended to achieve decay ratio. Reaction rate method a method of tuning a controller based on open-loop response to a step input.
