I would like to ask about some terms of control engineering.

What are other common expressions for "moving a pickoff point" which can be used as" moving a pickoff point behind of a block" or as "moving a pickoff point ahead of block."

Thank you.

"pick-off point" seems good enough. "tap point" is one alternative.

PS. If you are writing something, I recommend that you avoid a variety of terms and just use one standard term all the way through. I have spent hours upon hours wondering if some term in a document meant something different from another similar term, when they really meant the same thing.

Could "node", too, be alternative of them ?

Thank you.

"node" is a good general term. If you want to imply that the node is a place where a signal is being observed or split off to another place, "pick-off point" implies that and is better.

I am not sure but some people might call summing junctions as substractors.

Thank you.
 

What is control engineering?

Control engineering is a branch of engineering that deals with the design, implementation, and management of systems that are able to regulate and control physical processes. It involves the use of mathematical models, algorithms, and computer software to control and optimize the behavior of systems.

What is a control system?

A control system is a collection of components that work together to adjust the behavior of a physical system. It typically consists of sensors, controllers, actuators, and feedback mechanisms, and is designed to maintain a desired output or performance of a system.

What is feedback control?

Feedback control is a method used in control engineering to adjust the behavior of a system based on information received from sensors that monitor the system's output. The controller uses this feedback information to make adjustments and maintain the desired performance of the system.

What are the different types of controllers used in control engineering?

There are three main types of controllers used in control engineering: proportional, integral, and derivative (PID) controllers. Proportional controllers adjust the output based on the difference between the desired and actual values, integral controllers correct for sustained errors, and derivative controllers anticipate changes in the system and adjust accordingly.

What is system identification in control engineering?

System identification is the process of using data from a system to identify its mathematical model. This involves collecting data from the system's inputs and outputs, and using techniques such as data analysis and system identification algorithms to create a mathematical model that describes the behavior of the system.
