FREQUENCY-RESPONSE ANALYSIS

ECE4510/5510: Feedback Control 1 FREQUENCY-RESPONSE : Motivation to study FREQUENCY-RESPONSE methods Advantages and disadvantages to root-locus design approach:ADVANTAGES: Good indicator of transient response. Explicitly shows location of closed-loop poles. Tradeoffs : Requires transfer function of plant be known. Difficult to infer all performance values. Hard to extract steady-state response (sinusoidal inputs). FREQUENCY-RESPONSE methods can be used tosupplementroot locus: Can infer performance and stability from same plot . Can use measured data when no model is available. Design process is independent of system order (# poles). Time delays handled correctly (e s ). Graphical techniques ( ANALYSIS /synthesis) are quite simple. What is a frequency response? We want to know how a linear system responds to sinusoidal input, insteady notes prepared by and copyrightc 1998 2017, Gregory L.

The above plots are in a natural scale, but usually a log-log plot is made This is called a “Bode plot” or “Bode diagram.” Reason for using a logarithmic scale Simplest way to display the frequency response of a rational-polynomial transfer function is to use a Bode Plot .

ECE4520/5520: Multivariable Control Systems I. 6–1 STATE-FEEDBACK CONTROL 6.1: State-feedback control We are given a particular system having dynamics x.t/P D Ax.t/CBu.t/ y.t/D Cx.t/CDu.t/: We know that open-loop system poles are given by eigenvalues of A. Want to use input u.t/ to change the dynamics.

• Voltage is constant. Period. OCV v(t) i(t) − − + + This model is inadequate, but provides a starting point. • Batteries do supply a voltage to a load. • And, when the cell is unloaded and in complete equilibrium (i.e., “open circuit”), the voltage is fairly predictable. • An ideal voltage source will be part of our equivalent ...

Battery State Estimation

mocha-java.uccs.edu

Model-based state estimators implement algorithms that use sensor measurements to infer the internal hidden state of a dynamic system. System Model Measured Output Predicted Output Input Process Noise Sensor Noise True System State State Est. A mathematical model of the system is assumed known. Same input propagated through true system and model.

Elements of Plot, continued Falling Action happens as a result of the climax and we know that the story will soon end. Resolution is when the character solves the main problem/conflict or someone solves it for him or her. Denouement (French: the action of untying): is the series of events that follow the plot's climax.

The intensity looks like the plot below versus position y, where y. z. are the minimums (or zeros): Intensity . y. 1. y. 2. y. 3. Minimums (zeros, y. z) y . Minimums are caused by the destructive interference of plane waves diffracting off the edges of the slit. Destructive interference happens when two plane waves are out of phase to one another.
