Abstract

In this paper, Linux-RTAI and Matlab/RTW is used to develop real-time control system for fast real-time simulation and implementation of the control algorithm. The hardware of the controller is based on PC/104 cards under Linux-RTAI operating system. The main characteristic of Matlab/RTW is that it can automatically generate the real-time simulation code for many target processors. The combination of Linux-RTAI as a controller platform and Matlab/RTW as control algorithm development environment brings the two main advantages: hard real-time capability and reduced time for control development. Moreover, online signal monitor and parameter modification is realized on the whole structure system. At last, the minimum execution time of real-time control task is determined and the application of real-time control system into flight vehicle is achieved in the work.
