Realization of Networked Control Based on Simulink in Embedded System

With the broad application of embedded systems in the networked control systems at present, a new method that can make Simulink block diagrams run in embedded systems using Matlab/Simulink/Real-Time Workshop is introduced in this paper. A platform of the embedded system based on ARM7TDMI cpu core with uClinux operating system is built, at the same time, the hardware and software interfaces are developed as well as the means to control the plant. This method is verified by the experiment for the control of the motor speed with PID control algorithm. It provides users with a convenient and quick way to test control algorithms in a real-time hardware platform. By this means, the results of the control algorithms running in the embedded system, which connects to a real controlled plant, can be monitored, on-line tuning of the control algorithms can be implemented easily , in addition, supervisory control based on the Internet can be realized. This method reduces the experiment costs and shortens the development period.
