DARTS: a low-cost high-performance FPGA implemented real-time control platform for adaptive optics

Translation is a multimedia dance performed on a vertical wall filled with the projected image of a lunar surface. Pendaphonics is a low-cost, versatile, and robust motion-sensing hardware-software system integrated with the rigging of Translation to detect the dancers' motion and provide real-time control of the virtual moonscape. Replacing remotely triggered manual cues with high-resolution, real-time control by the performers expands the expressive range and ensures synchronization of feedback with the performers' movements. This project is the first application of an ongoing collaboration between the Motivational Environments Research Group at Arizona State University (ASU) and STREB Extreme Action Company.

Control Education

Arduino microcontrollers are popular, low-cost, easy-to-program, and have an active user community. This paper seeks to quantitatively assess whether or not Arduinos are a good fit for real-time feedback control experiments and controls education. Bode plots and serial echo tests are used to assess the use of Arduinos in two scenarios: a prototyping mode that involves bidirectional real-time serial communication with a PC and a hybrid mode that streams data in real-time over serial. The closed-loop performance with the Arduino is comparable to that of another more complicated and more expensive microcontroller for the plant considered. Some practical tips on using an Arduino for real-time feedback control are also given.

Design Ideas

In order to realize the sensor signal acquisition and analysis of data, according to data acquisition system design ideas of the PCI bus, applying to CPLD complex programmable controller and CH365 interface chip and combined with the actual needs of data collection ,designed a kind of low cost, high speed process controller. CPLD realizes data cache control and the control of reading. This design can gather 16 roads analog signals and real-time pulse signal of 8 roads on the same time, which includes a 16-bit digital output channel and a 32-bit counter, could be used in the real-time control.

Modern Industry

Ethernet has been broadly used in modern industry for its exoteric standard, flexibility and low cost. Ethernet is becoming the right choice for many engineering application. However, issues of performance must be considered when we apply it to timing sensitive field such as real time control system and so on. An Ethernet interface solution implemented based on s3c2410a and ax88796 was described in this article, and in order to improve the performance, inline assemble was introduced into this study. The effect of performance improvement through inline assemble was checked by ping experiments. It was proved that inline assemble can improve the performance of Ethernet interface distinctly.
