Proportional-integral-derivative (PID) guide

Tutorial: Motion-control architectures
It's not just improved motors and MOSFETs that matter; architectures play a key role in modern motion control. This tutorial explains your options and the characteristics of each.

The basics of control system design:

• The basics of control system design: Part 1 - Moving beyond PID
  In the first of articles over the next six days, George Ellis, author of "Control System Design Guide," compares and contrasts various approaches to embedded Proportional-Integral-Derivative (PID) control system design.

• The basics of control system design: Part 2 - Tuning a Proportional Controller
  In the second of a series of articles over six successive days, George Ellis, author of "Control System Design Guide," compares and contrasts various approaches to embedded Proportional-Integral-Derivative (PID) control system design. In this installment: tuning a proportional controller.

• The basics of control system design: Part 3 - Tuning a PI Controller
  In the third of six articles over successive days this week, George Ellis, author of "Control System Design Guide," compares and contrasts various approaches to PID control systems. This time, tuning a PI controller.

• The basics of control system design: Part 4 - Tuning a Pl+ Controller
  In the fourth of six articles over successive days this week, George Ellis, author of "Control System Design Guide," moves beyond proportional and PI controllers talk about tuning a PI+ controller and other related topics.

• The basics of control system design: Part 5 - Tuning a PID Controller
  In the fifth of six articles over successive days this week, George Ellis, author of "Control System Design Guide," compares and contrasts tuning a digital PID controller to analog versions and to controllers using the Ziegler-Nichols Method.

• The basics of control system design: Part 6 - Tuning PID+ and PD controllers
  George Ellis, author of "Control System Design Guide," concludes a six part series of articles on various approaches to Proportional-Integral-Derivative (PID) control system design with a discussion of the PD and PID+ configurations comparing them to the other P, PI, PI+ and PID methods discussed earlier in the series.

Using simulation software to simplify DSP-based Electro-Hydraulic Servo Actuator Designs:

• Using simulation software to simplify DSP-based Electro-Hydraulic Servo Actuator Designs: Part 1
  Richard Poley describes the basics of electro-hydraulic servo systems and how to use Matlab's Simulink to do "hardware-in-the-loop" design a DSP-based control system.

• Using simulation software to simplify DSP-based Electro-Hydraulic Servo Actuator Designs: Part 2
  In Part 2, TI's Richard Poley shows how to develop basic mathematical equations of relationships in an electro-mechanical system and use Simulink to model them.

• Using simulation software to simplify DSP-based Electro-Hydraulic Servo Actuator Designs: Part 3
  Richard Poley describes the modeling of a typical servo actuator, using Matlab's Simulink to do "hardware-in-the-loop" design of a DSP-based control system.
