Answer:
Concept:
A control system uses control loops to manage, command, direct, or govern the behaviour of other equipment or systems. It can range from a single thermostat-controlled boiler in a single-family home to massive industrial control systems that are used to manage whole production lines. A feedback controller is used to autonomously control a process or operation for constantly modulated control. The control system compares the desired value or setpoint (SP) with the value or status of the process variable (PV) being controlled and uses the difference as a control signal to bring the processing variable output of the plant to the setpoint. Software logic, such as that found in a programmable logic controller, is utilized for sequential and combinational logic.

Answer:
Impulse, step, ramp, and parabolic signals are the typical test signals. Utilizing the output's temporal response, these signals are used to gauge the performance of the control systems. A standard test signal in telecommunication is a single-frequency signal with a standard level that is used to evaluate the peak power transmission capacity and measure the overall harmonic distortion of circuits or components of an electric circuit. The step size of the test signal, which is stated as the percentage change P in the correction unit, is called the step size.
As a percentage of the full-scale range, the controlled variable's output reaction to such an input is measured and shown as a graph versus time.Impulse, step, ramp, and parabolic signals are the typical test signals. Utilizing the output's temporal response, these signals are used to gauge the performance of the control systems. Test signals aid in system performance prediction since the input signals we provide are known; as a result, we can observe the system's output reaction to a specific input and comprehend the behaviour of the control system. Impulse, ramp, step, and sinusoidal signals are some of the most often utilized test signals.
