In order to study grasss rotary compression characteristics during round bundle process, measurement and control system for silage cylindrical baler was developed in this paper based on virtual instrument technology. The system was constituted of KM520-B silage cylindrical baler, three-phase asynchronous motor, frequency converter, sensors, data acquisition card, the LabVIEW software platform, and so on. This system can be used to acquire information such as forming chambers rotary compression pressure, motors input torque and motors power consumption. By controlling the motors input rotate speed, this paper studied the motor speed, the grass moisture content and the grass bale densitys influence on compression power consumption, grass bale forming quality and forming chambers rotary compression pressure. At the same time, this paper established simulation equipment using MAX of NI Corporation to check the built measurement and control system. The results proved that the system can well complete the set of functions.

This paper presents the composition and working principle of the hardware and software of the measurement and control system based on VeriStand and Simulink for a tracked model vehicle. The hardware of the system is composed of a CompactRIO controller and acquisition cards, torque/speed sensors and a gyroscope. The vehicle control logic model and data processing model are built in Matlab/Simulink. VeriStand is adopted to manage models and interact with people. The system can control motor speed on both sides of the vehicle and collect data such as sprocket torque and speed, vehicle attitude on real-time. At last, we test and verify the system can work successfully.

Graphical Programming Language

This paper deals with an implementation method of component-based Petri nets system based on a graphical programming language (LabVIEW). LabVIEW is not only a graphical programming language, but also a virtual instrument platform which is widely used in virtual measurement and control system. The Places (token number) of Petri nets are represented by Numeric Controls of LabVIEW. The Transitions of Petri nets are represented by subVIs of LabVIEW. Transition subVI will change the tokens of Places by the Numeric Controls' Reference when it is fired. This method will make it ease to implement a Petri net by simply combining Place and Transition components (subVI). The example implementing a special Petri net shows that the Front Panel of the controller reflects the system operating state directly; the Block Diagram is similar to the topology of original Petri net. The combination of two graphic languages makes the modeling, analysis and formal verification of measurement and control system based on Petri nets easier.

Step Control

The paper describes a control and measurement system for controlling and analysing operation of a stepper motor. The system design is based on the concept of virtual instrument, where data acquisition and transmission use standard solutions, whereas software serves both as a generator and a measurement system – an oscilloscope. The generator allows efficient control of motor operation in the following control modes: wave, full-step and half-step control. There were no winding powering sequence errors observed. The measurement system allows presenting and analysing voltage waveforms in individual windings with possibility to detect couplings and overvoltages. It was also shown that it is possible to detect locking of rotor rotation.The proposed virtual instruments have open structure, which enables extended analysis based on available measurements or expand range of measurements as long as measurement and control system instrumentation allows that.
