PI Controller for Solving Simple Equations

EasyChair Preprint 5320

Abstract

PID control is a true workhorse for industrial process control. Its widespread use in various control applications is highly contributed by its astonishing property of removing a control error between the targeted setpoint and the controlled variable. The very same feature, however, can also be utilized for other purposes where zero error is required. Solving an equation is good example of such dilemma. In this paper, the PI controller is presented as a solver e.g. for computing square roots, solving quadratic equations with real-valued solutions and linear equations of two variables.

Keyphrases: PID control, equation, linear, solution
