COORDINATE CALCULATION SYSTEM USING PROPORTIONAL-INTEGRAL-DERIVATIVE ALGORITHM AND LOCATION POSITION APPARATUS USING THE SAME SYSTEM

摘要

PURPOSE: A coordinates calculation system using a PID control algorithm and a location measure system using the same for simplifying a complex process are provided to perform the real-time coordinate calculation in a node. CONSTITUTION: A distance measuring unit(150) measures a distance between a target node and an arbitrary node based on a reference node. An error producing unit(170) produces the error distance between the target node and the arbitrary node. A PID controller(110) applies the error to a PID control algorithm. The PID controller produces the control variable. A coordinate controller(130) calculates the coordinate of the arbitrary node by using the control variable.
