What is a control system?

A control system is a system, which provides the desired response by controlling the output. The following figure shows the simple block diagram of a control system.

How to formulate a state space controller with an integrator?

To formulate a state-space controller with an integrator in it, add a model of a unknown bias input (ubias) into the plant model. Feeding back the estimated ubias will form an integrator in the compensator (state estimate feedback) and accomplish the same thing.

How do error signals work in a control system?

Instead of the direct input, the error signal is applied as an input to a controller. So, the controller produces an actuating signal which controls the plant. In this combination, the output of the control system is adjusted automatically till we get the desired response.

What is the difference between Siso and MIMO control systems?

SISO (Single Input and Single Output) control systems have one input and one output. Whereas, MIMO (Multiple Inputs and Multiple Outputs) control systems have more than one input and more than one output.
