Project Summary

Flight control algorithms play a vital role in dynamics and control of any aerial vehicle. Better performance or efficiency of any aerial system cannot be achieved without a stable and robust controller.  A lot of researches are already available in the domain of conventional airplane or UAV, but research is very limited in case of space vehicles. This study aims to design, simulate and develop a flight control system algorithm for anti-satellite missiles. The anti- satellite missiles are designed to track and destroy any target satellite using the conventional payload. Development of feedback control system has been studied by using the conventional techniques. The research started with extensive literature survey, for mathematical modeling of nonlinear dynamic system of the atmosphere and missile. PID, LQR and AI based controllers were studied for application to our specific problem. Implementation of Euler angles and quaternion has also been kept the under consideration. Implementation of new techniques such as machine learning and deep learning has also been reviewed under this study. The designed controller would be tested using the requisite software (STK and MATLAB), the missile would be tasked to identify and track the target satellite using the sensors and imagery data and perform maneuvers to attain its path / orbit at a higher velocity and ultimately destroy it. 6 DoF simulation would be made using the controller results.  

Project Objectives

In this project, the major objective is the development of  the feedback control system of third Stage of the anti-satellite missile. The controller should control the thrusters of the missile for the change in trajectory. Control systems will be developed using PID, LQR, and Deep Learning techniques.

Project Implementation Method

This project methodology / development has been divided into seven phases which are given below,

Phase 1: CAD and Aerodynamic Analysis

Adequate CAD and aerodynamic model of specified anti-satellite missile should be developed using different soft wares such as CATIA V6 and ANSYS Fluent. This phase will help us in the development of stability derivatives and process of the assumptions for the linearization of mathematical models.

Phase 2: Mathematical Modelling

The second phase of the development of this project starts with theoretical Mathematical modeling of missile using 6 DOF using quaternions. The missile dynamics can be represented by using the 6 degree of freedom non-linear partial derivative equations having the six-coupled force and moments. This phase will also contain the mathematical modeling of Earth and motion of target satellite using the available techniques.

Phase 3: Linearization of Mathematical Models

Linearization of developed six degree of freedom nonlinear equations will be done using different techniques and linearization theories for its application. Different applicable assumptions will be applied while keeping error in mind.

Phase 4: Application of Control Techniques

This process will start with the development of control design conditions for the 3rd stage of the missile. PID and LQR controlling techniques will be applied in this phase for the best results.

Phase 5: Simulation of anti-satellite missile

This phase starts with the programming of the Control system of the 3rd stage of the Anti-satellite missile. Development of Simulation for the control system of Anti-Satellite missile will be done using python and MATLAB.

Phase 6: Development of intelligent control system

This phase will start with the development of different machine learning and deep learning model for control system. Different techniques will be studied, and the most appropriate technique will be used for the development of control system.

Phase 7: Implementation of feedback control system on microcontrollers

This phase will start as the procurement of required sensors and microcontroller which are feasible for this application. The developed designed of the control system will then be converted into required form. So that, it could be applicable on the micro-controllers. Implementation of designed control algorithm / code will be done on microcontroller in this phase.

Phase 8: Testing and analysis of developed control system

After the successful implementation of control system, the developed control system will be tested in ideal conditions for its working. A detailed analysis will then be performed for its proper functioning and meeting in design conditions.

Phase 9: Development of prototype

A small-scale model of rocket / missile will be created in laboratory for testing. Different test's will be conducted for the proper functioning of control system under specific conditions.

Benefits of the Project

Peace and stability in the south Asian region are one of the basic goals of our country for the prosperity and benefit of all nations. In 2019, the Indian successful experiment of anti-satellite missile has created an unstable environment of peace and power in South Asia. India has always been an major adversary to Pakistan and fought three conventional wars with Pakistan. Satellites are becoming one of the major threats to Pakistan, as they could be utilized for unfair means. In wartime, their Indian satellite could be used to weaken the Pakistani defense system. The anti-Satellite missile will help us out in the defense of our country by destroying the satellite of our adversary. The development of an Anti-Satellite missile will help out Pakistan to balance the power and peace in this south Asian region.

There are also some technical benefits of this project, which are given below,

1. The mathematical which will be developed in this process could be utilized for any missile dynamics. Mathematical modeling could be used as a reference for the development of rocket/ missile control systems that could be developed in the future using the future techniques that will be available at that time.
2. The developed control system in this project will be able to control the 3rd stage of the anti-satellite missile to follow its trajectory using different control techniques. This system could be utilized for the development of the Anti-Satellite Missile.
3. The developed data set that will be going to be utilized in the training of the controller of a feedback control system using a different machine and deep learning techniques can be utilized for future training with new techniques. This data set could also be used for the training of rockets going with the same trajectory.
4. The application of emerging technologies will open a new gate of innovation for the development of missile control systems that could help us in the near future. Where such techniques are going to be widely used for the development of rocket and missile control systems. The use of machine and deep learning could help us to get out of the complex conventional development of control systems. Mathematical modeling and other complex steps will be cut out using these emerging technologies. These technologies are easy to deploy which makes them a perfect candidate for futuristic missile and rocket control systems.
