Many force feedback virtual reality simulators use linear actuators. However, available linear actuators sufferfrom a significant cogging response during operation. This is a significant complication since the forcefeedback response should feel analogous to the forces experienced in reality. In the proposed research project, acogging-free linear actuator will be developed. This will be achieved by redesigning the magnet packing andthe use of ferromagnetic material in the motor to obtain a uniform magnetic field rather than developing anadditional means of control.The development of the new clogging-free actuator technology will underpin Iris' ambition to expand salesbeyond its current niche market of force-feedback flight yokes into Helicopter Cyclics and motion platformsused for helicopter simulation which require high precision force-feedback response. In addition, the projectwill directly serve the West Coast Wave Initiative's development of a sustainable energy technology solution byproviding cost-efficient simulators for the development of Wave Energy Converters which must provide forcefeedback that mimics the reactions of the actual system.

许多力反馈虚拟现实模拟器都使用线性执行器。然而，可用的线性致动器在操作期间遭受显着的齿槽响应。这是一个严重的并发症，因为力反馈响应应该与现实中经历的力类似。在拟议的研究项目中，将开发无齿槽线性执行器。这将通过重新设计磁体封装以及在电机中使用铁磁材料以获得均匀磁场来实现，而不是开发额外的控制手段。新的无堵塞执行器技术的开发将巩固 Iris 扩大销售的雄心。当前力反馈飞行操纵杆的利基市场用于直升机循环和运动平台，用于需要高精度力反馈响应的直升机模拟。此外，该项目将通过为波浪能转换器的开发提供经济高效的模拟器来直接服务于西海岸波浪倡议的可持续能源技术解决方案的开发，波浪能转换器必须提供模拟实际系统反应的力反馈。
