Design FPGA speed controllers for air motor

This paper uses the field-programmable gate array (FPGA) controller on air motor system. The proportional-integral (PI) and model reference adaptive control (MRAC) theories are actualized by the hardware description language (HDL) code. In circuit designs, modular conception is used to divide a complex system into many parts. This methodology reduces the development time and easy to debug for each module. In this research, the chip was produced by ALTERA company and LP-2900 FPGA design lab was produced by LEAP electronics. From experimental results, the chattering range was between the 0.6% and 1.8%. The FPGA speed controllers have good performance in air motor system.
