Nejat Control Gain Series Method

Abstract

Fuzzy logic control and digital logic control are in two different realm of control systems because one is dealing with uncertainty of true or false (Fuzzy) and the other one is based on either true or false that is in most cases 0 and 1 (digital). In this paper, there is an attempt to introduce a method that can be used to tune either Fuzzy logic control and digital logic control. Nejat Control Gain Series Method is created by the author to reach the desire output and in some cases to stabilize a SISO or MIMO system in order to achieve desired output(s). It uses series of gains in the system by multiplications and divisions, in the other word: gaining up and gaining down of the systems by placing gains at multiple locations in a system. It is a good method when using controller and notch filter in a system. By multiply the open loop input by gain to increase or decrease the magnitude of a system and then divide the output by another gain to increase decrease the magnitude of a system in which a controller and Notch filter would be designed based on these back and forward gain multiplication and divisions. This Method is compared PID controllers, gain scheduling to show its efficiency. Just to note, gain scheduling is usually being used for non-linear control system.
