Think Again: The 2019 Control Engineering Career and Salary Survey includes questions on topics of concern, such as outsourcing, workforce, process improvement, cybersecurity, automation, and threats.Current and Previous Research Areas (See Publications By Category) Iterative Learning and Repetitive Control Work in these fields started with visiting scholar Sun Jian-Guo in 1983, and also resulting in a first paper by Richard Middleton, doctoral student, and Prof.
Work accelerated so that there are now approximately 180 publications in this area by the research group.
Iterative Learning Control (ILC): Feedback control systems do not do what you ask them to do.
Iterative learning control aims to eliminate all such errors in following a specific command repeatedly, by adjusting the command given to the feedback control system based on the error observed in the previous run.
Initial motivation of the field came from robots doing repetitive tracking operations in manufacturing.
Classical control theory treats steady state frequency response of linear systems, and a command of one frequency produces an output of the same frequency but with the wrong amplitude and the wrong phase.
In addition there is error during the transient phase and there is error from disturbance effects that often are the same every time the same command is given.

System Identification: Before one can design a control system one needs a model of the plant to be controlled. It is distributed by NASA and it was ordered by most of the major aerospace companies in the US.
If the plant hardware is available one can make input-output experiments to collect data that allows you to create a mathematical model. The approach develops the steady state Kalman filter from input-output data first, and from this result it backs out a state space model of the system.
