Professor Owen was involved in the late 1990s in Austin, Texas, in the development of Fisher Rosemount's DeltaV distributed control system. At Cal Poly he pioneered the development of the Mechanical Controls Lab, bringing computer control into the lab and designing hydraulic and pneumatic motion control systems. He also was involved, with others, in redesigning a two-tank level-control system for control using Simulink. He has also held controls lectures and taught in laboratories in Germany at the Munich University of Applied Sciences and at the Karlsruhe University of Applied Sciences and in Belgium at the University of Antwerp. He also worked over a two-year period in the Automation Lab at the University of Bergamo in Northern Italy. There Dr. Owen was instrumental in introducing the simulation of mechanical systems for the purpose of designing motion controllers for them.
The following tutorials were created to lead you through the process of understanding Control Systems Engineering
The internal signals in a control loop are enumerated and described in this video. How information flows between the components of a control loop is explained.
Describes the difference between these two basic types of control loops: how they function, what the aim of each is, how their configurations differ, how non-zero signals propagate through each loop.
Two very common examples of these two types of control loops is given to make clear the different operation of these two types of loops. A fly-by-wire system illustrates the operation of a positioner loop. An automotive cruise-control system illustrates the operation of a regulator loop.
Shows the details of an autonomous guided vehicle developed at the Laboratorio di Automatica at the University of Bergamo in Northern Italy.
A system to actuate the muscles of the thigh for a person with a severe back injury to allow him/her to move his/her lower leg for physical therapy.
Shows a standard procedure for producing a block-diagram model of a dynamic system from its ODE (ordinary differential equation). This is shown for a mass-spring-damper system, but this technique can be applied to any dynamic system whose dynamics is represented by an ODE, even mulitple-degree-of-freedom systems.
The response of a first-order dynamic system to a step input is explained.
Describes what the closed-loop transfer function is and how to obtain it from a standard control-loop block diagram.
Explains the difference between these two concepts and discusses why this is so confusing in the study of classical Controls
Describes the three-part function of the PID controller and its block-diagram structure.
Describes a classification scheme for control systems used in the German-speaking world. A very shorthand notation can be used to describe even complicated systems..
In 2010 Professor Owen reacted to the high price of Controls textbooks (around $200) and wrote his own, Control Systems Engineering: A Practical Approach. It can be ordered from Dr. Owen for a price of $25 plus shipping and handling
