At present, commercial variable speed drives require a shaft mounted speed sensor to operate accurately at zero and low speeds. The operation of the drive at zero and low speeds deteriorates significantly if no speed sensor is used. A new technique for sensorless control of variable speed ac motor drives has been researched in EPSRC Grant EP/D069017/1. The technique provides accurate control of motor speed, position and load, even at zero and very low speeds, without the need for a shaft mounted speed sensor.The aim of the work described in this proposal is to demonstrate that this new technique is flexible and robust enough to enhance and upgrade the performance of commercial variable speed ac motor drives, . The specific objective is to ensure that the technique can be applied to a wide range of different ac motors (from different motor manufacturers) and that the inverter can setup its control parameters automatically if appropriate. This plug and play , high performance sensorless control will allow the inverter to be used for a variety of new applications and for a wide range of power ratings. Before potential licensees are willing to invest in the technology, it is crucial to demonstrate that it can be used in plug and play mode with any ac motor. The technical work package within this Follow-on fund will deliver this proof thereby making successful commercialisation possible.

目前，商用变速驱动器需要安装在轴上的速度传感器，以便在零速和低速下准确运行。如果不使用速度传感器，则驱动器在零速度和低速下的操作显著恶化。在EPSRC Grant EP/D 069017/1中研究了一种用于变速交流电机驱动器的无传感器控制的新技术。该技术提供了精确的控制电机的速度，位置和负载，即使在零和非常低的速度，而不需要一个安装在轴上的速度sensor.The本提案中所描述的工作的目的是证明，这种新技术是灵活的和强大的，足以提高和升级的商业变速交流电机驱动器的性能，。具体目标是确保该技术可以应用于各种不同的交流电机（来自不同的电机制造商），并且逆变器可以在适当时自动设置其控制参数。这种即插即用的高性能无传感器控制将使逆变器能够用于各种新应用和广泛的额定功率。在潜在的许可证持有者愿意投资这项技术之前，证明它可以在任何交流电机的即插即用模式下使用至关重要。该后续基金中的技术工作包将提供这一证明，从而使成功的商业化成为可能。
