STATE-FEEDBACK CONTROL

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.

Equivalent-Circuit Cell Models

• 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

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.

State-Space Models and the Discrete-Time Realization …

Discrete-Time Realization Algorithm 5.1: Introduction to state-space models The coupled PDEs derived in earlier chapters of notes are too complex to be used in real-time applications. •They are “infinite dimensional.” For every point in time t, there are an infinite number of x- and r- dimension variables to solve for. •i.e., c s(x,r ...

KEY PERFORMANCE INDICATORS - Plant Maintenance

Identification and Performance Analysis elements. This is the continuous improvement loop. Actual asset performance is monitored relative to the required performance (driven by business needs). Performance gaps are identified. The ‘cause’ of these gaps is established and corrective action recommended. Performance Metrics for the Maintenance
