Proportional control, Integral control

In summary, proportional control is a type of feedback control system that adjusts the output based on the error in the input signal, while integral control adjusts the control signal based on accumulated error over time. When used together, they can improve system performance and stability, and are commonly used in industries such as manufacturing and robotics for temperature control, flow control, and motor speed control.

I want to know the proper nomenclature about control theory.

Problem is below.

" There is the system, which is controlled by P control or I control (anything is Ok.) where a is proportional gain and b is integral gain. When proportional gain, a is slightly changed, system output is big different. "

What is the proper nomenclature or name?
Which book is helpful for studying?

Could you explain what 'system output is big different' means?
 

FAQ: Proportional control, Integral control

What is proportional control?

Proportional control is a type of feedback control system in which the output of a system is adjusted in proportion to the error in the input signal. This allows the system to reach a desired setpoint by continuously adjusting the control signal based on the difference between the actual output and the desired output.

What is integral control?

Integral control is a type of feedback control system in which the control signal is adjusted based on the accumulated error over time. This helps to eliminate steady-state errors and improve the system's response to disturbances or changes in the input signal.

How do proportional and integral control work together?

Proportional and integral control are often used together in a control system to achieve better performance. Proportional control provides a quick response to changes in the input signal, while integral control helps to eliminate any steady-state errors. Together, they can provide a more stable and accurate control of the system.

What are the advantages of using proportional and integral control?

The use of both proportional and integral control can result in improved system performance, better stability, and faster response to changes in the input signal. Additionally, these control methods are relatively simple to implement and can be easily adjusted to optimize system performance.

What are some real-world applications of proportional and integral control?

Proportional and integral control are commonly used in various industries, including manufacturing, robotics, and process control. They can be applied in systems such as temperature control, flow control, and motor speed control to achieve precise and stable operation.
