Development of a Rapid Control Prototyping System Based on Matlab and USB DAQ boards

Abstract

Abstract:In this paper, we propose a new and cost-effective RCP (Rapid Control Prototyping) system based on Matlab/Simulink and a DAQ (Data Acquisition) unit with the high speed USB communication interface. The proposed RCP system has a feature that a computer on which Simulink is running acts as a realtime controller and a DAQ unit performs data acquisition, transmission of the data to and from a computer, and the application of control data received from the computer. For its implementation, we develop 10 communication blocks each of which is constructed by using S-function. In order to increase the data communication speed and thus to reduce the sampling period of the overall control system, we propose to use a batch transfer strategy through the USB interface. The proposed RCP system has several advantages over existing methods such as good maintainability, portability due to the USB interface, low cost, and no necessity for C-code generation even though it can only be applied to control systems with moderate sampling rates. It is expected that the proposed RCP system can be useful in teaching control-related topics to undergraduate and graduate students. [3][4][5][6][7]. 더불어 RCP 시스템의 적용에 대한 연구들도 다수 발 표되고 있다 [8,9].

“…A certain RCP system does not use the code generation approach. In that system, the Simulink controller model perform as a real-time controller (Lee et al, 2012). One can focus on the de-velopment of the control algorithm using the block diagram editing and doesn't have to be worried about the input/output peripheral handling based on manual coding.…”

“…Embedded coder, another add-on product of Simulink, generates C-code specific to a certain embedded processor and thus reduce the time for the development (Inc., 2005a). Matlab/Simulink and RTW are open architecture and thus several lab-developed RCP systems for custom-developed hardware have been proposed in academia (Rebeschieß, ;Hong et al, 2000;Lee et al, 2004;Hercog and Jezernik, 2005;Bucher and Balemi, 2006;Lee et al, 2012). Furthermore, several researches related with the application of RCP system are published (Lin et al, 2006;Kennel, 2006).…”

“…In this paper, we use the RCP system proposed in (Lee et al, 2012). The RCP system proposed in (Lee et al, 2012) utilizes a DAQ board with high speed USB communication interface and Matlab/Simulink. Because it uses a DAQ board with a microcontroller as a basic component, we will call the system as the DAQ RCP throughout the paper.…”

High-Level Modular Autopilot Solution for Fast Prototyping of Unmanned Aerial Systems

“…with a completely onboard implementation system. 2 Only solutions validated in flight are considered, thus excluding general purpose and/or educational approaches, such as [28], [29], [30], [31], [32], [33], [34]. In any case, the only redundant alternative is MAS PX4 .…”
