An Adaptive FPGA-Based Mechatronic Control System Supporting Partial Reconfiguration of Controller Functionalities

Using FPGA to design host-controller node of networked control system for construction machinery

“…According to the above requirements, thanks to FPGA (Field Programming Gate Array) technology and its own advantages such as hard-logic implementation of parallel trigger, reconfigurable, embedded processors [4], FPGA's application in the controller design has been widespread concerned recently [5]. An adaptive controllers using partially reconfigurable technology was designed to achieve the property that controller changes parts of its structure configuration on-line once external environment diversification is detected by the controller in order to save controller logic resources [6] [7]. Taking advantages of SOPC IPcores duplicating technology and features of totally custom hardware, as well as the principle of parallel processing, a flexible to configure controller was developed for the robot using FPGA to improve the control system flexibility and real-time performance [8].…”

A run-time reconfigurable FPGA-based drive controller for electrical drive systems

“…Hence, FPGAs provide an attractive platform for the implementation of drive, motion and actuation controller functionalities [1] [2]. The flexibility of an FPGA-based drive controller can even be increased by using partial reconfiguration features of modern FPGAs [3]. Partial reconfiguration of an FPGA enables the adaptation and reprogramming of functionalities, algorithms and parameters in hardware during the drive controller's run-time.…”

Power/Area Analysis of a FPGA-Based Open-Source Processor using Partial Dynamic Reconfiguration

“…Partial Dynamic Reconfiguration has been an extensive topic of investigation in the last decade with applications ranging from Satellite communication systems [1] and Erlangen Slot Machine [2] to adaptive control system [3], [4]. The advantages gained from reconfiguration have led to the research and development of a virtual internal configuration access port (JCAP) [5] in a Xilinx Spartan III platform, which does not support internal re-configuration by default.…”

“…The advantages gained from reconfiguration have led to the research and development of a virtual internal configuration access port (JCAP) [5] in a Xilinx Spartan III platform, which does not support internal re-configuration by default. For Self-Reconfiguration, it is possible to make use of an internal processor [1], [4], [5], [6] or a dedicated controller [2], [3], which resides inside the fabric in order to reprogram part of the system without interrupting the current running processes. The internal processors that have been extensively used to control Partial Dynamic Reconfiguration in the Xilinx family of devices have been the IBM PowerPC hard IP core and the MicroBlaze soft core processor.…”
