FPGA-Based Model-Free Nonlinear Control Approach with Application to First Order Delays System

Abstract

The Proportional-Integral-Derivative (PID) controller to control of first order delay system has fluctuations in presence of uncertainty. To reduce the rate of fluctuations as well as improve the first order delay rise time, the first objective is design a Proportional-Integral-Integral-Derivative (PI 2 D) controller. This algorithm is complex control technique which requires faster micro-controllers; therefore the second objective of this article is to present the implementation of the PI 2 D on the Field Programmable Gate Array (FPGA). The maximum output required time in PI 2 D is 32.88 ns and the maximum output frequency in PI 2 D algorithm is 30.4 MHZ.
