The speed control system of DC motor normally uses increasing of electric current and voltage for obtaining required speed and torque with regardless of effects from variable of load torque to system. Including that noise will make some errors in speed and torque control. This research aims to present a method for developing the high accuracy in speed control of DC motor by a technique of adaptive torque compensation that is evolved on Lyapunov stability and using Kalman filter for screening out the evident noises in the system. Results reveals that the adaptive torque compensator evolved from the Lyapunov stability can compensate a stable torque and when it is worked with Kalman filter, it can compensate torque correctly and can control more accuracy of motor speed.

AbstrakPenggunaan motor DC di dunia industri sangat penting. Kecepatan dan torsi motor DC sangat mempengaruhi kualitas dan kuantitas produk yang dihasilkan. Untuk itu, diperlukan sistem kontrol motor DC yang dapat diatur kecepatan dan torsinya. Banyak pelaku industri mengeluhkan kerusakan pada motor DC disebakan beban yang diangkut motor melebihi kemampuan torsi motornya. Berdasarkan permasalahan tersebut dibuatlah sistem kontrol torsi motor DC.Sistem kontrol torsi dibuat dengan cara mengatur arus armaturnya pada motor DC penguat terpisah dengan kondisi arus fieldnya tetap. Sistem kontrol torsi ini bersifat dua level yaitu, sistem kontrol kecepatan dan sistem kontrol arus sehingga sinyal keluaran sistem kontrol kecepatan akan menjadi sinyal reference arus.Pengujian dilakukan dengan beban maksimal 3690 gram dan arus nominal sebesar 0,8 A atau torsi nominal sebesar 0,323 Nm. Hasil menunjukkan torsi efektif motor mampu diatur dengan kisaran 0,182 Nm - 0,243 Nm. Diharapkan dengan harga torsi efektif yang diatur mampu menahan beban seberat apapun tanpa merusak motor tersebut.Kata kunci—  Motor DC, Kecepatan, TorsiAbstractThe use of a DC motor in the industrialized world is very important. Speed of DC motor and torque of DC motor greatly affects quality and quantity of product. Therefore, we need control system of a DC motor that can be set speed and torque. The number of industry players complained about damage to the DC motor because transported load torque of motor exceeds capabilities of torque of DC motor. Based on these problem, we should make torque control system in DC motor.Torque control system made by regulating armature current of DC motor separately excited with current field  constant condition. Torque control system consist of speed control and current control, namely control system two level. Output signal speed control system will be the current reference signal.Testing has been carried out with a maximum load of 3690 grams and a nominal current of 0.8 A or nominal torque of 0.323 Nm. The results shows the effective torque of motor is able to be set in the range of 0.182 Nm - 0,243 Nm. Expected to value effective of regulated torque is able to withstand infinite heavy loads without damaging the motor.Keywords—  DC Motor, Speed, Torque

The DC motor has good characteristics of large starting torque and good traction and strong overload capacity, traditional battery motor vehicle often adopts DC motor drives as driving system and uses the series resistance to adjust speed. However, in actual coal production, since motor vehicles are often placed in wet, explosive and dusty environment, the speed control system of motor vehicle has strict proof and moisture requirements, however, the inherent characteristics of the DC motor make it a serious shortcoming in the coal mine production, there is an urgent need to improve the structure to meet today's actual demand for coal mine automated production. This article is in this context, to compare the DC motor speed control system with AC speed control system of the mine car, discussing today's mainstream technical programs of AC speed control system, focus on the analysis of the great differences over performance and economic efficiency of the speed control system of mine motor vehicle after adopting AC speed control system.

<p>In this paper a dual open loop speed control system based on two independent PWM signals of small permanent magnet DC (PMDC) motors using PIC16F877A microcontroller (MCU) has been designed and implemented. The Capture/Compare/PWM (CCP) modules of the MCU are configured as PWM mode and the MCU is programmed using flowcode software package to generate two PWM signals with various duty cycles at the same frequency. A dual H-bridge channel chip SN754410 is used to drive the motors. The variation of PWM duty cycles is related directly to controlling the DC motors terminal voltage which directly proportional with speed of each motor. The complete PWM control system model has been simulated using proteus design suite software package. The development of hardware and software of the dual DC motor speed control system has been explained and clarified.</p>
