Abstract

A control actuation system has been used extensively in automotive, aerospace, and defense applications. The major challenges in modeling control actuation system are rise time, maximum peak to peak overshoot, and response to nonlinear system with percentage error. This paper addresses the challenges in modeling and real time implementation of control actuation system for missiles glider applications. As an alternative fuzzy-PID controller is proposed in BLDC motor drive followed by linkage mechanism to actuate fins in missiles and gliders. The proposed system will realize better rise time and less overshoot while operating in extreme nonlinear dynamic system conditions. A mathematical model of BLDC motor is derived in state space form. The complete control actuation system is modeled in MATLAB/Simulink environment and verified by performing simulation studies. A real time prototype of the control actuation is developed with dSPACE-1104 hardware controller and a detailed analysis is carried out to confirm the viability of the proposed system.

Summary

Introduction

Brushless DC motor drive is used extensively in process industries, robotics, aerospace, and home appliance. A motion controller is realized to control fins of missiles and gliders to reach their target for which a BLDC motor drive is used to control fins. BLDC motor has features of protracted performing viability, high dynamic response, and efficiency. BLDC motor response is the challenge task to control position fins in desired direction with reference to the steering command. A power electronics switching inverter is used to drive BLDC motor for control actuation system. The conventional PID control had been implemented in BLDC motor drive. These controllers suffer from drawbacks: lack of performance in nonlinear system and more rise time with oscillatory response [7,8,9]
