| Abstract | ||
| This research demonstrates the procedure for servo control circuit implementation for the guided missile. Motivated by enhancing the performance of the guided missile servo system control circuit by using embedded systems and gaining the digital circuit advantages and, solving the problem of obsolete analog components. The proposed servo system includes four servo pistons for driving the missile canard. A high-resolution gear potentiometer is used as positionfeedback for the missile fin. The guidance command converted from the polar form to cartesian and delivered as input to the microcontroller PIC18f4431 to control the pneumatic servo by generating corresponding pulse width modulation(PWM) to the driving circuit.In this regard System identification for the pneumatic servo system is carried out. In current work,a servo positioning system based on an embedded system was designed to achieve a deterministic time response and minimize the jitters around 155μs for accurate guidance and control operation. The accuracy of the controlled system was verified using servoAutomatic Test Equipment (ATE) and,the results show the enhancement in the platform performance based on digital implementation instead of the analog circuit | ||
