What is actuation?
Submitted by: lars Submitted on: September 29, 2003 Identifier: L1.1 “Actuation” refers to the means of effecting control on a given system. For example, the throttle (or, alternatively, the engine) is considered an “actuator” for the car in the cruise control example (equivalently, the actuation). In most of our examples, we will use the variable “u” as representing the control input to a system. For example, the throttle position (or the engine torque) is the control input in the cruise control example. The control input affects the system being controlled by means of its actuation.

Submitted by: lars Submitted on: September 29, 2003 Identifier: L1.1 Feedforward control is a mechanism of control in which the control is affected by a priori known or predicted disturbances. The term “feedforward” is used since it describes the forward (left-to-right) flow of signals in a standard block diagram. Feedforward control has its bene
