Peter Pon­ders PID — Introduction 

The purpose of this video is to inform the viewer about what to expect. My videos go much deeper than the typical videos. They are geared for graduate st... See More

Peter Pon­ders PID, Nat­ur­al Fre­quen­cy vs Fre­quen­cy of Acceleration 

This video is intended for servo hydraulic system designers and those that program hydraulic servo systems but it does show how several of the techniques sho... See More

Peter Pon­ders PID — Cas­cade Con­trol Part1 

I cover whether cascade control is necessary. Why there needs to be a feed back for every loop. How to calculate gains. Bode plots and ratio of the inner t... See More

Auto Tun­ing a Small DC Motor in Torque Mode 

I was really testing the picture in picture feature of the Screen Flow software I use to make these videos. I knew the auto tuning would work. I kept the v... See More

Peter Pon­ders PID — Closed Loop Zeros 

This video covers closed loop zeros, what causes zeros and the benefits and drawbacks of closed loop zeros. See More

Peter Pon­ders PID — Cas­cade Con­trol Part2 

The inner loop pole locations and gains are calculated first so the inner loop pole locations are determined by the user. The outer loop poles are still pla... See More

Peter Pon­ders PID — Con­trol­ling a non-inte­grat­ing sin­gle pole sys­tem. Part 3 

Part 3 uses PI control which is the only practical means of control a non-integrating single pole system.http://deltamotion.comhttp://forum.deltamotion.com See More

Peter Pon­ders PID — IAE,ITAE,ISE Per­for­mance indicators 

Performance indicators can be used to compute closed loop pole locations. Only one gain parameter is required to move the pole locations closer to the origi... See More

Peter Pon­ders PID — Con­trol­ling non-inte­grat­ing sin­gle pole sys­tem. Part 1 & 2 

Part 1 shows why P only control shouldn't be used because the set point or target is never reached.Part 2 shows why I only control shouldn't be used because ... See More

Peter Pon­ders PID. Sec­ond Order Plus Dead Time , SOPDT, Tem­per­a­ture Con­trol, long dead...

In this video I derive the equations for the controller gains and a low pass filter for a SOPDT system with a very long dead time To make the simulation mo... See More

Peter Pon­ders PID — Con­trol­ling an Under Damp Mass and Spring System 

Demonstrates:How to calculate the PID gains. The importance of the derivative gain. How to simulate the mass and spring systemControl limitations based on s... See More

Peter Pon­ders PID — Why PID with 2^nd Deriv­a­tive Gain? 

If you have ever tuned a hydraulic system and wondered why PID control didn't work better than PI control the answer is here. Since the 1980s people have kn... See More

Peter Pon­ders PID — Inte­grat­ed Time Absolute Error — 4 Pole example 

This video shows how to calculate the coefficients for a 4 pole ITAE and how to use the 4 pole ITAE to calculate closed loop controller gains. See More

Peter Pon­ders PID-Fuzzy Log­ic vs PID 

There are many academic and engineering papers showing how good fuzzy logic control is relative to PID control. Every FL vs PID paper I have seen compares... See More

Peter Pon­ders PID — T0P1 Part 4, Misc Topics 

This video covers another way to compute symbolic gains, the difference between having the P gain act on the error or just the feedback, extending bandwidt... See More
