Development of Software for 4-Wheel- Steering-System Applying Modern Control

摘要

A robust four-wheel-steering-system applying modem control has been actualized by using 16 bit microcomputer. In order to bring control logic to practice, a block diagram is transferred to numerical formula. And to satisfy the microcomputer's performance such as ROM/RAM capacity and operation execution rate, the control logic has been simplified and numerical formula has been transferred from floating point form to integer form. By limiting the control operation area and preventing under flow and over flow, it is proved that simplification of logic and transformation of floating point form to integer form have no effect on control performance.
