FPGA-based accuracy mechatronics of a feed-drive system with ball screw

High-accuracy mechatronic systems require a control algorithm to realize trajectories or positions. On the other hand, the acquisition of data and embedded system design configurable is a very important part to guarantees processing in hardware, high performance, reception, and send of data that generally is defined by the applications to which it is intended. Therefore, the increasing demands in the improvement of the accuracy systems based on modern programable devices are being applied in the scientific and engineering areas. This paper presents a novel mechatronic approach to experimental validation of a feed drive system with ball screw. The description of an original FPGA-based configurable design is introduced which consists of an own design approaches of hardware architecture. Finally, based on a built prototype of a feed drive system with ball screw, the PID controller implemented and the mathematical model, in both cases, were applied in order to establish the comparison between the responses, seeking to observe if the experimental results show a great difference with respect to the simulation data. A cost-effective solution using a single chip low-cost FPGA for feed-drive system is presented to the closed-loop control present approximately the same response as that of the system model used in the simulation. Experimental results demonstrate an excellent positioning control and processing performance of the data configured on the FPGA Firmware, which validates the feasibility and effectiveness of the proposal.
