Based on TMS320F2812 multiple spindle movement control card design
Monday, October 5th, 2009 at 04:04 | No commentsCategories: DSPShort Content: Introduction The open style architecture's numerical control system has become now the numerical control technology development direction, but based on the computer standard main line "the PC movement control card" the structure will be the next open style numerical control technological development mainstream. This kind of numerical control system usually selects high speed DSP to take movement control card CPU, uses main from the type control policy, reads the memory using PC and DSP the way to realize ... -
Based on MCU DSP motion control hardware platform design
Tuesday, July 7th, 2009 at 00:55 | No commentsCategories: DSPShort Content: Introduction The open style controller architecture stems from "open style" PC (personal computer) the technology, the present open style movement controller many are the PC movement control card structure, along with MCU (micro controller) and DSP (digital signal processor) the performance enhancement, MUC and DSP substitutes for PC the tendency to be day by day obvious, but this kind of embedded compact structure compares PC to have more widespread adaptability to environment. MCU, DSP and the PC difference is ... -
Realizes between the motion control and the data acquisition synchronized using the RTSI main line
Monday, December 8th, 2008 at 02:22 | No commentsCategories: Communication NetworksShort Content: Abstract: In order to increase the measuring accuracy, many test system request the real-time synchronization carries on the data acquisition in the continual motion. According to the synchronous working principle, has realized between the motion control and the data acquisition synchronization using the RTSI bussing technique and the LabWindows/CVl programming, the experimental result indicated that this method in the enhancement test precision aspect is effective. Key word: Synchronization; RTSI main line; Motion control; Data acquisition 1 introduction Many test system request ... -
Based on FPGA high speed PID controller design and simulation
Saturday, November 22nd, 2008 at 03:12 | No commentsCategories: EDA/PLDShort Content: In CNC (computer numerical control) processes, the laser cutting, the automated roll arc welding system, to step-by-step/the servo motor control and other by in the motor control machinery assembly setting movement control system, the PID controller applies widely. Its design technique is mature, since long formed the model structure, the parameter installation has been convenient, the structure change was flexible, could satisfy the general control the request. This kind of motion control system is accused the quantity ... -
Based on DSP NURBS curve interpolation control
Tuesday, November 4th, 2008 at 10:16 | No commentsCategories: DSPShort Content: Abstract: This article introduced one kind based on TMS320LF2407the DSP chip's movement control card's design method and the NURBS interpolation's concept, proposed realizes the NURBS curve interpolation one real-time method, uses based on the parameter recursion estimate and the adjustment parametric curve interpolation algorithm, simplified in the interpolation process trajectory computation effectively, has avoided to the curve direct derivation and the radius of curvature and so on complex computation, this algorithm obviously reduced the interpolation computing time, can thus adapt ...
