Abstract
The present invention is directed to a method of and an apparatus for detecting an angular velocity and a rotation angle of a rotary member. In the present invention, first and second accelerations at first and second points of the rotary member are detected, respectively. The first and second accelerations are added, while the first acceleration is subtracted from the second acceleration. From the added and subtracted values, then, an angular velocity and a rotary angle of the rotary member are calculated.
Claims17
A method of detecting control information, comprising the steps of:
- detecting first and second accelerations at first and second points of said rotary member, respectively;
- subtracting said first and second accelerations to obtain a subtracted value;
- calculating a rotation angle of said rotary member on the basis of said subtracted value;
- generating a first signal representing said rotation angle using the subtracted value;
- generating a first control input based on said first signal;
- and
- controlling a motor disposed to drive said rotary member based upon said first control input.
An apparatus for detecting control information, comprising:
- a rotary member;
- a motor for driving said rotary member;
- first and second sensors for detecting first and second accelerations at first and second points of said rotary member, respectively;
- a subtracter for subtracting said first acceleration from said second acceleration to obtain a subtracted value;
- a second computation unit for calculating a rotation angle of said rotary member on the basis of said added value and for outputting a first signal representing said rotation angle;
- and
- a motor control unit for generating a first control input, and controlling said motor on the basis of said first control input.
