Motor overheat is a common problem in the field of haptics rendering. Typically, haptic system manufacturers include some sort of overheat protection in haptic devices, either by shutting down the device or reducing the maximum current when measured temperature reaches dangerous levels. However, the existing heating protection techniques are not efficient as they generally do not use the current state of the motor in addressing the problem. More precisely, they mainly use a fixed protection system regardless of the operating condition of the motor. In this proposal, a novel temperature control mechanism is considered to use the model of the DC motor in the haptic system to estimate the current condition of the motor and generate a compensating feedback control signal, in an adaptive fashion, accordingly. Advanced model-predictive control techniques will be used to generate the control signal. Furthermore, optimization methods will be used to minimize the effect of heating compensation in the overall performance of the haptic system.

电动机过热是触觉渲染领域的常见问题。 通常，触觉系统制造商通过关闭设备或减少测量温度达到危险水平时，包括触觉设备中的某种过热保护。 但是，现有的供暖保护技术并不有效，因为它们通常不使用电动机的当前状态来解决问题。 更确切地说，无论电动机的工作条件如何，它们主要使用固定保护系统。 在此提案中，一种新型的温度控制机制被认为使用触觉系统中的直流电动机模型来估计电动机的当前状况，并以自适应方式生成补偿反馈控制信号。 先进的模型预测控制技术将用于生成控制信号。 此外，将使用优化方法来最大程度地减少触觉系统整体性能中加热补偿的影响。
