What is ramp input in control system?

Ramp input represents a constant change in the input to a control system. For example, velocity with constant acceleration in a motion control system is a ramp input.

What is ramp input signal?

A ramp function or ramp signal is a type of standard signal which starts at 𝑡 = 0 and increases linearly with time. The unit ramp function has unit slop.

What is ramp function in process control?

The ramp function is a unary real function, whose graph is shaped like a ramp. It can be expressed by numerous definitions, for example "0 for negative inputs, output equals input for non-negative inputs".

What is meant by step input ramp input and impulse input?

With the step input we have the input suddenly being switched to a constant value at some particular time. With the impulse input we have the input existing for just a very brief time before dropping back to zero. With the ramp input, we have the input starting at some time and then increasing at a constant rate.
