Performance comparison between variants PID controllers and unity feedback control system for the response of the angular position of the DC motor

Abstract

This paper proposed a detailed study for the response of angular position of the rotor of a DC motor. It is a comparative analysis to the behavior of the DC motor when the motor is alone and when it is with controllers. Furthermore, a comparison between the responses of controllers themselves. A conventional PID controller which was tuned by using Ziegler and Nichols method was proposed in this paper. Also, Modification PID controllers were proposed in this paper. The modification PID controllers are PI-D controller and I-PD controller. Mathematical calculations were done to get the transfer functions for the DC motor and the controllers. Time domain specifications and figures were obtained for each case by using Matlab program. The obtained results were summarized in tables. This paper determined which the controller is the best one depending on the obtained figures and the time domain specifications.

Intelligent Control of Inter Distance in Convoy of Vehicles Using Model-Free Control and Algebraic Filter

“…This strategy consists in using a series of spring-damper unit between each pair of adjacent vehicles to ensure safety between the vehicles of the convoy, in which case it is necessary to adjust the distance between the vehicles to a pre-assigned value. As a result, the spring-dampers unit is used to represent the interaction forces between the vehicles of the convoy, a local speed controller PID [11][12][13][14] is designed for each vehicle. In order to study the robustness of the considered approach, we decided to make a synthesis study between two techniques of the same family but in two different contexts.…”
