| Abstract | ||
| Digital PID controllers are widely used in industrial applications. They are used in autopilots, ship steering, and speed control of machines…etc. A digital computer with an interfacing device is used to implement such types of controllers. In this paper, the design of digital controller using FPGA is described. The design provides a minimization in the hardware design and reduction in the cost as compared with the digital control implemented using digital computers. The structure of the controller can be selected using 2 bit input binary value. The type of the structures is P, PI, PD or PID. The parameters of the controller are tuned from the outside of the FPGA controller. In order to test the design, a discrete linear 1st order model is implemented inside the FPGA. Also, the closed loop system was simulated using MATLAB/SIMULINK program. A comparison between the simulated and designed systems shows that the results are very acceptable and close to each other. | ||
