What is algebraic loop

Question

Accepted Answer

An algebraic loop occurs when a system of equations has a circular dependency, making it impossible to solve for a unique solution.

An algebraic loop is a situation where the output of a block is fed back into the input of the same block or another block in a closed loop.
Algebraic loops can cause numerical instability in simulations and make it difficult to converge to a solution.
They are common in control systems, signal processing, and other engineering applications.
Example: In a control system, if the output of a controller is fed back into the input, creating a loop, it can lead to an algebraic loop.
