Position Control of a Cart Moved by DC Motor Using PV-DFC Method Supported by Balloon Effect
Abstract
This paper presents an application to servo controller for DC motor systems by a design of both robust disturbance feedback control (DFC) and Balloon effect (BE) are used to avoid bad effect of external load disturbance which the traditional controller fall in face it.
Traditional controller such as Proportional – integral – derivative (PID), Proportional - integral (PI), and 2 Degree Of Freedom (2DOF-PID) are the most popular controller at industrial application. In this paper used Position-Velocity (PV) conventional controller and PID. With an additional loop processed the output of system and the controller signal which called DFC, additional to BE which is a gain to improve the mathematical model of DC motor.
The proposed methods are compared to conventional controllers on a servo motor system. They have been tested by step load disturbance and simulation results supported the importance of the DFC and the role of BE.
