NOTE
Devices are necessary to control how machines work, in such a way that the task is performed as desired.
A dynamic control systems is a system that
- evolve over time
- have inputs and outputs.
Control Objectives
- Stabilization: make sure the plant does not deviate too much from the desired behavior
- Performance: Execute the desired task as accurately as possible
- Robustness: perform well even in the presence of external disturbances
Course Objectives
In the course we will do:
- Modeling: learn how to represent a dynamic control system in such a way that it can be treated effectively using mathematical tools.
- Analysis: understand the basic characteristics of a system (e.g., stability), and how the input affects the output.
- Synthesis: figure out how to change a system, typically by feedback, in such a way that it behaves in a desirable way.
We will be focusing on: SISO: systems with a single input and a single output LTI: linear time-invariant system
