In the subject area of control theory, an internal model is a process that simulates the response of the system in order to estimate the outcome of a system disturbance. The internal model principle was first articulated in 1976 by B. A. Francis and W. M. Wonham [1] as an explicit formulation of the Conant and Ashby good regulator theorem. [2]
Murray Corporation of America run from 1600 Clay Street, Detroit Michigan was, from 1925 until 1939, a major supplier of complete automobile bodies to the Ford Motor Company. Non-automotive stamped steel products were added during the Great Depression of the 1930s.
Mammalian model systems like mice and monkeys offer the most straightforward comparative models for human health and disease. They are widely used to study the role of higher brain regions common to vertebrates, including the cerebral cortex, thalamus, basal ganglia and deep brain medullary and reticular circuits for motor control.

Richard M. Murray is a synthetic biologist and Thomas E. and Doris Everhart Professor of Control & Dynamical Systems and Bioengineering at Caltech, California. [1] [2] He was elected to the National Academy of Engineering in 2013 for "contributions in control theory and networked control systems with applications to aerospace engineering, robotics, and autonomy".

A motor controller is a device or group of devices that can coordinate in a predetermined manner the performance of an electric motor. [1] A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and electrical ...
Its name comes from the information path in the system: process inputs (e.g., voltage applied to an electric motor) have an effect on the process outputs (e.g., speed or torque of the motor), which is measured with sensors and processed by the controller; the result (the control signal) is "fed back" as input to the process, closing the loop.
Tom Homan, President-elect Donald Trump’s incoming border czar, told NBC News on Friday afternoon that he is pitching the "fresh idea" of a hotline for Americans to report immigrants they ...
Every control system must guarantee first the stability of the closed-loop behavior. For linear systems, this can be obtained by directly placing the poles. Nonlinear control systems use specific theories (normally based on Aleksandr Lyapunov's Theory) to ensure stability without regard to the inner dynamics of the system. The possibility to ...
