Electric drive systems employed in several industrial applications need higher performance, responsibleness, and skill to vary the speed. One among the enticing options of the dc motor over all alternative styles of motor is that the relative ease with that speed management may be achieved. During this paper, speed management of dc motor mistreatment GSM technology has been investigated. It's a closed-loop real time system, wherever the feedback circuit is coupled to the motor shaft to produce the feedback speed signal. A mobile phone is hooked up to the feedback circuit that is a trigger. The PWM signal are send to motor driver to vary the voltage provide to motor. GSM (SMS) controlled dc motor is automatic control system which capable of receiving a set of command instructions in the form of short message service and performs the necessary actions like start stop and speed control. We will be using a dedicated modem/mobile at the receiver module i.e., with the robot itself and send the commands using SMS service as per the required actions. The mobile unit which is dedicated at the motor driver is interfaced with an intellectual device called micro controller so that it takes the responsibility of reading the received commands in the form of SMS from the mobile unit and perform the corresponding predefined tasks such as motor start, stop, motor direction and speed control at different levels etc.

The electric drive systems used in industrial applications require higher performance and reliability. The DC motor is used in many industrial applications requiring variable speed and load characteristics due to its ease of controllability. Microcontrollers can provide easy control of DC motor. In this research work, implementation of the ATmega8L microcontroller for speed control of DC motor fed by a DC chopper has been investigated. The chopper is driven by a high frequency PWM signal. Controlling the PWM duty cycle is equivalent to controlling the motor terminal voltage, which in turn adjusts directly the motor speed. A prototype of permanent magnet DC motor speed control system using the microcontroller is developed and tested.

Over the past decade, research efforts have been made to decrease the number of power electronic devices needed in multi-motor drive systems in order to condense the overall complication and cost of the drive. This paper proposes speed control for a dual three-phase induction motor system driven by five-leg voltage source inverter (FL-VSI) which is used in industrial manufacturing processes. Industrial applications frequently need a number of variable speed electric drives. This technique uses five-leg inverter instead of using conventional two three phase inverters. In the majority of cases, these multi-motor drive systems need independent control of individual motors. It is shown recently that it is possible to separately control two three-phase induction machines supplied through a five-leg voltage source inverter, with one inverter leg being common to both machines. The entire performance of the speed control for the five leg voltage source inverter fed dual-motor drive system is investigated using MATLAB/SIMULINK software.

Reliable, smooth, and fault free speed control of a Permanent Magnet (PM) DC motor using an H-bridge is an important need for many industrial applications such as robotics, automotive, and process industry to improve the overall efficiency and productivity. The reliability of H-bridge depends on the semiconductor switches used. The faults in these components can lead to a complete failure of the system. This paper presents a dual redundancy-based fault-tolerant system with a Fault Detection and Isolation (FDI) unit that can detect, isolate, and replace the faulty switch with the standby to prevent the unwanted shut down of the system and support the process continuity thereby increasing reliability. MATLAB/Simulink environment was used for simulation experiments and the results demonstrate the stable operation of the motor in the events of faults while maintaining its speed. The presented work establishes that the dual redundancy-based fault-tolerant H-bridge with the FDI unit is a highly reliable solution for the speed control of a DC motor.
