A bearingless permanent magnet synchronous motor (BPMSM) control system has a large number of control variables but has a small amount of data variables. So, adopting optimal coding scheme is demanded in its human-computer interaction. Based on the analysis of data format in serial port communication and data types of control variables, an optimal scheme of data split and combination and a coding...
Advancement in technology is very well reflected and supported by changes in measurement and control instrumentation. To move to high-speed serial from Parallel bus architectures has become prevalent and among these Ethernet is the most preferred switched Serial bus, which is forward-looking and backward-compatible. Great stride have been made in promoting Ethernet use for industrial networks and...
In order to prevent the glass from scratching and mildewing in storage and transportation, the anti-mildew powder should be added between the glass. For the demand of the powder spraying, the electrostatic powder sprayer control system based on PLC was developed. Spraying constant powder for the middle - part glass of variable thickness realized by controlling two frequency converters respectively...
The size and complexity of large-scale distributed embedded systems such as automotive and process controls have increased recently. Sophisticated systems that are safe and environmentally friendly require numerous types of sensor data, which are collected from various devices and sent to computers through networks. To develop such large-scale distributed embedded systems with high dependability and...
