Download: Prototyping a DC motor PI Controller Using FPGA
A Proportional-Integrate controller was implemented on a single-chip Xilinx Field Programmable Gate Arrays (FPGA). The controller was designed for angular position control of a DC servomotor. The FPGA was designed in Handel-C language, using Fixed-point numbers. The PI controller took approximately 1% of the total look-up-tables of a Xilinx virtex v1000 FPGA, and had a maximum clock rate of 4.6MHz.
The prototyping environment consisted of an FPGA evaluation card, a data acquisition card that has 8 channels on-board ADC and two DAC, and a computer with Windows NT4.0 operation system.
This goal of this work is to evaluate the FPGAs’ performance in digital control applications.
Detailed experimental results were shown in this report. It was concluded that FPGAs have sufficient computation power for some custom digital control applications.

Hello there! This is a good read. I will be looking forward to visit your page again and for your other posts as well. Thank you for sharing your thoughts about systems engineering jobs. I am glad to stop by your site and know more about systems engineering jobs. Keep it up!
The use of the term "system engineer" has evolved over time to embrace a wider, more holistic concept of "systems" and of engineering processes. This evolution of the definition has been a subject of ongoing controversy, and the term continues to be applied to both the narrower and broader scope.
Identify, define, and manage signal, power, data, and hydraulic, pneumatic, and fluid interfaces among subsystems. That's systems engineering jobs
