A novel real-time simulation platform for testing control algorithm

In this paper, a novel real-time simulation platform, used to test the control algorithm, is presented. The platform consists of three parts, which are Matlab/Simulink, PLC and dSPACE. Matlab/Simulink plays the role of controller along with PLC (Programmable Logic Controller), dSPACE simulation system is used to model the real controlled plant, the controller and controlled plant form a closed-loop real-time control system. Both the hardware connection and the communication realization of the platform are described in detail. The platform makes full use of the powerful data processing capabilities, abundant toolboxs of Matlab/Simulink and the profuse modeling methods in dSPACE, it's straightforward and flexible to realize the algorithm and model the controlled plant. Taking the parameter adaptive fuzzy PID as example, the simulation results explicitly show the effectiveness of the platform.
