A compensation scheme is proposed for plants subject to both saturation and backlash in series at the actuator. It is shown that the series connection of a backlash inverse, saturation and the backlash itself is equivalent to a saturation function at a different level to the original saturation; we call this the 'saturation equivalence'. Therefore it is proposed to include such a backlash inverse in the compensator. This is shown to be optimal in a sense defined in the paper.It is then straightforward to devise a compensator scheme based on traditional anti-windup. This is illustrated in both simulation and on a laboratory scale rig with severe backlash. A correction for the chattering observed in the control signal due to the discontinuous nature of the nonlinearity inverse is also presented.

“…The modular and reusable nature of Vis, and therefore their suitability for integration into cost-effective systems is underlined in [17]. Addi-tional benefits from having students collaborate in VI development is that these then reflect student interests and needs, as described, along with already mentioned advantages, in [18]. With respect to magnetic materials properties, some advantages are also cited in [19], [20].…”

Electrical Machines Laminations Magnetic Properties: A Virtual Instrument Laboratory

et al. 2015

Abstract-Undergraduate courses in electrical machines often include an introduction to their magnetic circuits, and to the various magnetic materials used in their construction and their properties. The students must learn to be able to recognize and compare the permeability, saturation and losses of these magnetic materials, relate each material to its specific properties, and understand the impact of these properties on the major performance metrics of electrical machines. This paper describes a new test equipment setup and lab guide that helps students achieve these learning goals. The test equipment consists of two transformers of grain-oriented and non-grain-oriented electrical steel, transducers, a data acquisition (DAQ) board and a PC-based virtual instrument. The virtual instrument shows voltage, current and core flux time waveforms, the rms voltage versus current curves and, most importantly, the lamination material magnetic cycle. Students' laboratory work was organized into a series of experiments that guide their achievement of these magnetic materials-related abilities. Pre-and post-lab exams assessed student learning, which was shown to have increased significantly. Students' opinions of the relevance, usefulness and motivational effect of the laboratory was also positive.

“…Constraints in educational institution laboratories such as lack or high cost of appropriate instruments and test rigs, risk of equipment damage, limited time availability for laboratory periods, do even sometimes dictate the use of VIs based on computer simulations as shown in [6]. Other recent contri- butions [7,8,9] have also provided helpful notions on the modernization of laboratories using VIs.…”

Virtual Instruments offer new possibilities for the electrical machines students to visualize and understand facts and correlations that otherwise often require more or less difficult calculations to be performed beforehand. The recent trend on the introduction of Data Acquisition systems (manipulated, accessed and controlled by means of VIs), either as new laboratory instruments or to substitute classic ones, opens a door to a new and very wide range of applications. This contribution shows the experience in this regard achieved in one of the electrical machines and drives laboratories of the
