The modern meaning is a scientific method to achieve a practical purpose.
Control Systems Technology includes all aspects of control engineering needed to implement practical control systems, from analysis and design, through simulation and hardware.
Experiments done by the research group on a robot at NASA Langley Research Center decreased the tracking error of the robot following a high speed command, by a factor of 1000 in approximately 12 cycles for learning.
Repetitive Control (RC): RC has two main focuses, one is to converge to zero tracking error in a feedback control system when given a periodic command, and the second is to converge to zero error for a constant command in a feedback control system that is subject to a periodic disturbance of known period.
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.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.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.Lucus Horta (NASA) after they finished their doctorates.Structural dynamics identification research also includes collaboration with Prof. Many of the results of the early part of this research can be seen in the textbook, Applied System Identification by Jer-Nan Juang, Prentice Hall, 1994. Lucas Horta, we developed the OKID (and SOCIT) algorithm, Observer Kalman Filter Identification algorithm.Many mechanisms perform periodic motions, and very often they are actuated using a feedback control system whose objective is to maintain constant input rotation rate.A series of publications study the use of RC System Identification, Damage Detection in Structures Research in this area started around 1987 working with Dr.A series of publications have been produced since that time.Mechanisms and Repetitive Control: Important contributions often occur at the interface between fields.
