CONTROL SYSTEM OF A PLANT EMBEDDED IN FPGA USING HARDWARE IN THE LOOP

Rapid prototyping systems are widely used in product development in the different industries. They provide the ability to set up the initial prototypes, test them under real conditions, and optimize them time- and cost-effectively, without extensive hardware development. Following the Hardware-in-the-loop concept, the operation conditions of a real system can be emulated by means of a mathematical model, embedded in an electronic device. This paper shows a thermal plant implementation in a FPGA, which emulates the real behavior and allows to assess the scope and benefits of HIL technique. On the other hand, a PID controller was designed in LabView ® to regulate the dynamics of the embedded plant by serial communication. A comparison was made to validate the system performance based on the design parameters.
