What Control is About???!!!
Indeed all modern systems (aircrafts, CD player, speed trains,
cruise control system, …) couldn’t operate without the aid of
sophisticated control systems.
Improved control is the key enabling technology underpinning
Enhanced product quality
Greater yield
Process: a series of operations acting toward the end
Sensors: machines which measure system output.
Actuator: the muscles or the part which does the action.
Disturbance: signals which affect the output.
Feedback: the measure of the output compared to target.
Open-loop system: the output is neither measured nor
fed-back.
Closed-loop system: the output is measured and compared with the
desired value.

Frequency Domain (Bode, Nyquest)
Modern Control
State Space (work for linear systems, have much control on
it)
Digital Control
Kalman Filters (estimate the variables that can’t be
measured)
Adaptive Control
Optimal Control
Robust Control
Intelligent Control
Neural Network
Fuzzy logic
Laplace Transform
Laplace transform: is a mathematical tool used to solve linear
ordinary
Differential equations ODE
Homogenous (transient equation +particular Integral (steady state)
of the sol.
Obtained in one operation
Obtain the s-domain solution, use the inverse transform to find the
time
domain solution.
S= a complex variable

Not valid if sF(s) contains a pole whose real part or zero is
positive
