2. Linear control - Wikipedia

   en.wikipedia.org/wiki/Linear_control

   Linear control. Linear control are control systems and control theory based on negative feedback for producing a control signal to maintain the controlled process variable (PV) at the desired setpoint (SP). There are several types of linear control systems with different capabilities.

3. Control theory - Wikipedia

   en.wikipedia.org/wiki/Control_theory

   Every control system must guarantee first the stability of the closed-loop behavior. For linear systems, this can be obtained by directly placing the poles. Nonlinear control systems use specific theories (normally based on Aleksandr Lyapunov's Theory) to ensure stability without regard to the inner dynamics of the system. The possibility to ...

4. Linear–quadratic–Gaussian control - Wikipedia

   en.wikipedia.org/wiki/Linear–quadratic...

   In control theory, the linear–quadratic–Gaussian ( LQG) control problem is one of the most fundamental optimal control problems, and it can also be operated repeatedly for model predictive control. It concerns linear systems driven by additive white Gaussian noise. The problem is to determine an output feedback law that is optimal in the ...

5. Control system - Wikipedia

   en.wikipedia.org/wiki/Control_system

   A control system manages, commands, directs, or regulates the behavior of other devices or systems using control loops. It can range from a single home heating controller using a thermostat controlling a domestic boiler to large industrial control systems which are used for controlling processes or machines.

6. Control engineering - Wikipedia

   en.wikipedia.org/wiki/Control_engineering

   Control engineering is the engineering discipline that focuses on the modeling of a diverse range of dynamic systems (e.g. mechanical systems) and the design of controllers that will cause these systems to behave in the desired manner. Although such controllers need not be electrical, many are and hence control engineering is often viewed as a ...

7. H-infinity methods in control theory - Wikipedia

   en.wikipedia.org/wiki/H-infinity_methods_in...

   H∞ (i.e. " H-infinity ") methods are used in control theory to synthesize controllers to achieve stabilization with guaranteed performance. To use H∞ methods, a control designer expresses the control problem as a mathematical optimization problem and then finds the controller that solves this optimization. H∞ techniques have the advantage ...

8. Linear system - Wikipedia

   en.wikipedia.org/wiki/Linear_system

   In systems theory, a linear system is a mathematical model of a system based on the use of a linear operator . Linear systems typically exhibit features and properties that are much simpler than the nonlinear case. As a mathematical abstraction or idealization, linear systems find important applications in automatic control theory, signal ...

9. Classical control theory - Wikipedia

   en.wikipedia.org/wiki/Classical_control_theory

   Classical control theory is a branch of control theory that deals with the behavior of dynamical systems with inputs, and how their behavior is modified by feedback, using the Laplace transform as a basic tool to model such systems. The usual objective of control theory is to control a system, often called the plant, so its output follows a ...
