Introduction to control: class 2 / 3

29 março 2017, 09:00 • Duarte Pedro Mata de Oliveira Valério

SISO LTI ODE models:

- using the Laplace transform to obtain transfer functions;
- state-space representations;
- obtaining time responses;
- unit-step and unit-impulse responses;
- responses to sinusoidal inputs;
- frequency response (gain, phase, Bode diagram).

Exercises about different representations of the model of a plant.
