PPT-Lecture 14: Stability and Control II

Reprise of stability from last time The idea of feedback control Remember that our analysis is limited to linear systems although we will apply linear control to nonlinear systems sometimes successfully. 118 brPage 2br Exponential Stability The origin of is exponentially stable if and only if the linearization of at the origin is Hurwitz Theorem Let be a locally Lipschitz function de64257ned over a domain Let be a continuously differentiable functi AS if for every trajectory we have as implies is the unique equilibrium point system is locally asymptotically stable LAS near or at if there is an R st 0 k as Basic Lyapunov theory 122 brPage 3br often we change coordinates so that 0 ie we use a Bi kh Bh tt ac arya Professor Department of Mechanical Engineering IIT Kanpur Joint Initiative of IITs and IISc Funded by MHRD brPage 2br NPTEL Mechanical Engineering Modeling and Control of Dynamic electroMechanical System Module 2 Lecture 14 In Before discussing the stability test let us rst introduce the following notions of stabilit y for a linear time invariant LTI system 1 BIBO stability or zero state stbaility 2 Internal stability or zero input stability Since we have not introduced t NSTX-U.

The main contributor to the static directional stability is the fin. Both the size and arm of the fin determine the directional stability of the aircraft. The furt Airplane Flight:.

We want to be able to control them —. to make a robot trace a particular path, say. TCP. . Peter Key. MSR Cambridge. Outline. Simple TCP models. Utility Maximisation - a framework for fairness.

Transfer Function is the ratio of Laplace transform of the output to the Laplace transform of the input. Consider all initial conditions to zero.. Frequency response concepts and techniques play an important role in control system design and analysis. . Closed-Loop Behavior. In general, a feedback control system should satisfy the following design objectives:. Basics of Control. Spring 2018. CS 599.. Instructor: Jyo Deshmukh.
