What is the control theory of control systems?
Control theory is a branch of Applied Mathematics dealing with the use of feedback to influence the behaviour of a system in order to achieve a desired goal.
One can distinguish two classes of systems for which control theory plays an indispensable role, namely man-made systems and biological systems..

Ogata s Modern Control Engineering, 5/e , offers the comprehensive coverage of continuous-time control systems that all senior students must have, including frequency response approach, root-locus approach, and state-space approach to analysis and design of control systems.

This book introduces important concepts in the analysis and design of control systems. Readers will find it to be a clear and understandable textbook for

How does a controller produce the integral control action?

For a small jet-nozzle displacement x,the flow rate q to the power cylinder is proportional to x; that is, For the power cylinder, where A is the power-piston area and r is the density of oil

Hence where constant

The transfer function Y(s)/X(s) is thus The controller produces the integral control action

Y(s) X(s) = K s K = K 1(Ar) = dy dt

What are the performance characteristics of a control system?

Frequently,the perform- ance characteristics of a control system are specified in terms of the transient response to a unit-step input,since it is easy to generate and is sufficiently drastic

(If the response to a step input is known,it is mathematically possible to compute the response to any input

)

A compensator is a component in the control system that is used to regulate another system.
Usually, it is done by conditioning the input or the output to that system.
There are three types of compensators: lag, lead and lag-lead compensators.
