| Abstract | ||
| Electromagnetic Servo Relay Drive (ESRD) devices are small, simple and reliable devices. Special types of ESRD Utilizing Pulse Width Modulation (PWM) technique to input driving voltage are used in guidance and control systems. In this Paper a simulation, using MATLAB and Simulink were performed. To improve the rising time and time response of the mechanical armature angular position, the input voltage has been selected to do that. Two techniques have been proposed, first is the PID compensator and second is the reshaping / reforming the input pulse voltage. The effects on the different system parameters has been declared and discussed in addition to the comparison between the two used methods. Results show that the 2nd method is more effective and give an improvement in star sting and rising time by about 20% compared with 6% improvement in 1st method. The second method shows an increment in power consumption which lead in heat dissipation. | ||
