Closed-loop transfer function — A closed loop transfer function in control theory is a mathematical expression (algorithm) describing the net result of the effects of a closed (feedback) loop on the input signal to the circuits enclosed by the loop. Contents 1 Overview 2… … Wikipedia
loop transfer function — noun The ratio of the Laplace transform of the primary feedback signal of a control system to that of the actuating signal Syn: loop ratio … Wiktionary
Feedback linearization — is a common approach used in controlling nonlinear systems. The approach involves coming up with a transformation of the nonlinear system into an equivalent linear system through a change of variables and a suitable control input. Feedback… … Wikipedia
Describing function — The Describing function (DF) method of Nikolay Mitrofanovich Krylov and Nikolay Bogolyubov is an approximate procedure for analyzing certain nonlinear control problems. It is based on quasi linearization, which is the approximation of the non… … Wikipedia
Minor loop feedback — is a classical method used to design stable robust linear Feedback control systems using feedback loops around sub systems within the over all feedback loop.[1] The method is sometimes called minor loop synthesis in college text books,[2][3] some … Wikipedia
Quantitative feedback theory — (QFT), developed by Isaac Horowitz (Horowitz, 1963; Horowitz and Sidi, 1972), is a frequency domain technique utilising the Nichols chart (NC) in order to achieve a desired robust design over a specified region of plant uncertainty. Desired time… … Wikipedia
Multiple feedback topology (electronics) — Multiple feedback topology is an electronic filter topology which is used to implement an electronic filter by adding two poles to the transfer function. A diagram of the circuit topology for a second order low pass filter is shown in the figure… … Wikipedia
Full state feedback — (FSF), or pole placement, is a method employed in feedback control system theory to place the closed loop poles of a plant in pre determined locations in the s plane. Placing poles is desirable because the location of the poles corresponds… … Wikipedia
Linear feedback shift register — [ xor gate provides feedback to the register that shifts bits from left to right. The maximal sequence consists of every possible state except the 0000 state.] A linear feedback shift register (LFSR) is a shift register whose input bit is a… … Wikipedia
Control theory — For control theory in psychology and sociology, see control theory (sociology) and Perceptual Control Theory. The concept of the feedback loop to control the dynamic behavior of the system: this is negative feedback, because the sensed value is… … Wikipedia
