Embedded FMS has many advantages, such as control flexibility, simplicity, good real-time, low cost etc. Open CNC system integrated embedded FMS can solve the existing problems between traditional NC system and industrialized production of NC application software. This paper adopts the structure of “NC embedded PC type”, designed an open CNC system based on the IPC and movement control card. The open...
A method is designed for the simplification of multi-function motion controller, based on the DSP I/O space and CPLD. The core technology is the use of the rich I/O space of the DSP and the powerful logic capabilities of CPLD. Using this method, the reuse of the DSP bus can be achieved. Compared with the traditional motion controller, the simplified motion controller significantly reduces both the...
A cost-efficient way to achieve high-accuracy motion control is the utilization of complex control algorithms. Hence advanced motion control constitutes a class of real-time applications, for which the technical feasibility strongly depends on the achievable execution performance on the embedded processing platform. The presented modular controller structure defines a set of advanced control algorithms...
When composing the control system of a spherical intelligent robot which is based on the image identification, a single chip control method does not have a fast data processing and high movement controlling capacity under the prerequisite of a small system, high precision and a fast response. This paper proposes a double-chip distribution control system based on the newly designed TMS320DM6437 and...
The paper presents a novel method for constructing soft servo networked motion control system via EtherCAT network. The EtherCAT network performance is analyzed in detail through comparison of it by other several industry Ethernet protocols. We give out the application PLC program flow chart of synchronous control. The experiment results show that the soft servo networked motion control system can...
This paper presents a comprehensive comparison of several real-time motion controller topologies implemented on a field programmable gate array (FPGA). Controller topologies are selected as proportional-integral-derivative controller with command feedforward, sliding mode controller, fuzzy controller, and a hysteresis controller. Controllers and other necessary modules are developed using Verilog...
This paper details the implementation of a hardware genetic algorithm used to evolve a digital circuit capable of controlling the motion of a robot. The digital circuit was a virtual FPGA comprised of functional elements layered in four columns. The virtual FPGA was configured by a bit stream generated by the hardware genetic algorithm which supports only mutation. The robot was in the form of a simulated...
Motion controller is one of the core components in construction machinery equipment. Compared with general-purpose motion controller based on PC or PLC, embedded motion controller (EMC) for construction machinery is characterized by the strong pertinency and specialty for this field. This paper describes the key technologies on developing the hardware and software of EMC for construction machinery,...
Traditional high-pressure water jet cutting adopts duplex reciprocating intensifier to generate high-pressure water. In order to solve the problems of water pressure fluctuation generated, the abrasive water-jet cutting machine based on phased intensifier is designed, and the structure of cutting machine as well as the hardware structure and working principle of phased intensifier are introduced,...
