Question

I am the project manager for the design and development

phases

of a new missile program for the Department of Defense. I

have

hired your team as a software design sub-contractor. Your

contract

requires you to design the program logic for a simplified

Sidewinder guidance control system. The Sidewinder is an

air-to-air

missile, and was the first to be effective in its mission.

The

reason for its success is its guidance control system. The

real

Sidewinder guidance control system is complex (see

http://science.howstuffworks.com/sidewinder6.htm for an

interesting

description of the real thing if you want), but I want you

to

design a simplified version of it for a new variant of the

missile

that my company has to introduce.

Basically, your software will receive a signal indicating that

a

target has been sighted. (It is obtained from the infrared

signature of your target, but all you need to know is that

you

receive a signal.) You will also know that the signal is

coming

from a particular angle from the missile's current course. If

the

target is off to the missile's left, you will receive data

that

tell you that it is x degrees from the current heading of

the

missile, and the number will be negative. If the target is off

to

the missile's right, you will receive data that tell you that it

is

x degrees from the missile's current heading, and the number

will

be positive. You receive these data points every second.

Based on what you know about how far off track you are, you send

a

signal to the servo assembly that controls the fins on the

missile.

The signal that you send is proportional to the angle of

error

between the missile's heading and the target. You will divide

the

angle of error by 10, and round it to the nearest whole number.

For

example, if your target is 22 degrees off to your right, you

will

send a value of +2 to the servo assembly controller. If your

target

is 36 degrees off to your left, you will send a value of 4 to

the

servo assembly controller.

Notice that I am only asking you to handle yaw (the

side-to-side

motion of the missile). Based on your performance on this

project,

I may contract with you to handle the pitch (up and down)

control

software. It would work similarly

Explanation / Answer

Basically there are five functions in the program i have used which execute as we call.
