Development of a DC motor control

Development of a DC motor control / Nasrul Hadi Hazal
Sebuah motor DC boleh beroperasi tanpa menggunakan apa-apa pemandu tetapi dengan berbuat demikian, motor akan dirompak daripada potensi yang sepenuhnya contoh seperti punyai kawalan kelajuan yang lebih baik. Dengan itu, projek ini telah dilaksanakan dengan mempunyai 3 objektif untuk menyelesaikan isu tersebut. Salah satu daripadanya adalah untuk membangunkan pemacu motor dan kawalan sistem DC berdasarkan mikropengawal Genuino Uno dengan paparan LCD dan papan kekunci. Satu lagi objektif ialah untuk mengintegrasikan kawalan PID gelung tertutup ke dalam sistem untuk meningkatkan prestasi kawalan motor di bawah beban atau tanpa beban. Akhir sekali ialah untuk mengimplementasikan sistem kawalan modul ke dalam satu prototaip kawalan pemacu motor DC dan menguji prestasinya. Berdasarkan objektif-objectif ini, metodologi yang telah dirancang ialah lukisan litar, penulisan kod, pembinaan prototaip, dan pengujian prestasi pemacu. Ujian ini dibahagikan kepada 2 bahagian: tiada analisis beban, dan analisis di bawah beban dengan setiap bahagian diuji dengan mengunakan cara kawalan yang berbeza. Parameter prestasi yang dipertimbangkan dalam penilaian adalah masa penetapan, peratusan terlajak, dan masa tindak balas ralat. Parameter dibandingkan untuk motor tanpa pengawal pemacu, pengawal P, pengawal PI , dan pemacu pengawal PID. Daripada keputusan parameter itu, pengawal PID dan pengawal PI didapati mempunyai prestasi yang lebih baik berbanding dengan semua kaedah kawalan yang lain. Pengawal PI mempunyai masa penetapan dan masa tindak balas ralat tetapi ianya juga mempunyai peratusan terlajak yang besar, manakala pengawal PID mempunyai masa penetapan dan masa ralat tindak balas yang perlahan tetapi ianya mempunyai peratusan terlajak yang lebih kecil berbanding pengawal PI. _______________________________________________________________________________________________________ A DC motor can operates without any driver but by doing so, the motor will be robbed of is full potential such as having a better speed control. With that in mind, this project was done by having 3 objectives to solve the issue. One of it is to develop a DC motor drive and control system based on Genuino Uno microcontroller with LCD display and keypad interface. Another one is to integrate a close-loop PID control to the system to improve the performance of motor control under load or without load. Last but not least is to implement the modules and control system into a single, simple DC motor control prototype and test its performance. Based on those objectives, a methodology was planned including circuit drawing, code writing, and constructing the prototype, and testing the controller performance. The testing was divided into 2 parts: no load analysis and under load analysis with each part tested on different controller scheme. The performance parameters that were considered in the evaluation are the settling time, percentage of overshoot, and error response time. The parameters were compared for motor with open-loop driver, P controller, PI controller, and PID controller driver. From the result, PID controller and PI controller were found to have better performance compared to all the other control methods. PI controller has better settling time and error response time but has a huge percentage of overshoot while PID controller has slower settling time and error response time but smaller percentage of overshoot compared to PI controller.
