Robust PID Control Parameter Design by Taguchi Method

PID robust control using Taguchi Method

The control of FOPD (first order plus delay) systems with high normalized time (ratio of time delay and time constant) is a very hard task, especially when the system parameters are subjected to variations. A great number of physical systems show such model behavior. In process control today, proportional integral derivative (PID) (continuous and digital) controllers still predominate and are s...

Robust Design and Taguchi Method Application

Robust Design of SAW Gas Sensors by Taguchi Dynamic Method

This paper adopts Taguchi's signal-to-noise ratio analysis to optimize the dynamic characteristics of a SAW gas sensor system whose output response is linearly related to the input signal. The goal of the present dynamic characteristics study is to increase the sensitivity of the measurement system while simultaneously reducing its variability. A time- and cost-efficient finite element analysis...

A Bayesian Method for Robust Tolerance Control and Parameter Design

This paper proposes a Bayesian method to set tolerance or specification limits on one or more responses and obtain optimal values for a set of controllable factors. The existence of such controllable factors (or parameters) that can be manipulated by the process engineer and that affect the responses is assumed. The dependence between the controllable factors and the responses is assumed to be ...

A Robust Design of MMIC using Taguchi Method

In this paper, we demonstrate a robust design of Monolithic Microwave Integrated Circuits (MMIC) using Taguchi Method. In accordance with Taguchi Method, noise factors, which are uncontrollable sources of variation, and control factors, which are available to control both the deviations and the mean-values by circuit designers were assigned to an orthogonal array. We simulated radio frequency (...
