Reconfigurable And Network Motion Controller Based On System On Programmable Chip

Motion Controller is widely used in industry, national defense, and people's daily life. However the architecture of current motion controller has many shortcomings, such as huge size, not supporting network communication, and difficulty when changing functions. These have made current motion controllers isolate from the outer world, and great resource be wasted when upgrade. Aiming at solving these problems, this paper does some research on the architecture of motion controllers.This paper firstly analyzes the common architectures that are used in many motion controllers, and points out their problems at size, communication, flexibility. With the aim of performance scalable and function extendable, proposes a new motion controller architecture, featured with single-chip, hardware reconfigurable and network and introduce system-on chip technology, reconfigurable hardware and embedded solution that be used in designing this new motion controller. In this architecture, the function is divided from top to bottom.In order to realize the proposed architecture, use SOPC that is the integration of Nios soft processor and large-scale programmable gate array to achieve hardware platform. During designing hardware system, do some works according to the design process of SOPC and study the method and process of IP cores. At the same time, another two IP cores is constructed using VHDL Hardware Description Language. This two IP cores are three phase Sinusoidal Pulse Width Modulation (SPWM) conversion and signal generation of DC motor control. In order to increase performance, uC/OS-II, a kind of real time operating system, is introduced into software design. Carve up the software system and use this operating system to manage tasks and pass parameter.Finally, build a test platform. The prototype system is tested in terms of remote control and hardware reconfiguration. The result show that, users can control a remote motor by sending commands in a WEB browser, and simply replacing the signal generation IP cores, users can control different type motors. This proves that the new architecture does well in intending controller's functions.
