Gyro/Stable Platform
Challenge:
Design a control system to maintain the line of
sight of an instrument mounted on a rotating platform.
Description:
This system is similar in nature to the control
problem encountered in instruments mounted on ships. A rate gyro is
mounted on the vertical shaft of a DC motor. The DC motor frame is
free to rotate about the vertical axis by an unknown amount. The gyro
deflection angle about the horizontal axis is measured using a sensor.
The desired outcome is to design a feedback controller
that measures the gyro deflection and maintains the line of sight of
the gyro frame independent of the unknown rotation at the base of the
frame. As an example, a radar beam aboard a ship is expected to point
in a fixed direction independent of the unknown yaw motion of the ship.
This is the same as requiring the line of sight of the gyro to remain
constant. The system is supplied with a PI controller. You may design
any other controller you wish.
