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.

电机过热是触觉渲染领域中的一个常见问题。 通常，触觉系统制造商在触觉设备中包括某种过热保护，当测量的温度达到危险水平时关闭设备或降低最大电流。 然而，现有的加热保护技术效率不高，因为它们通常不使用电机的当前状态来解决问题。 更确切地说，它们主要使用固定的保护系统，而不管电机的运行状况如何。 在这个建议中，一种新的温度控制机制被认为是使用模型的直流电机的触觉系统，以估计当前的电机状态，并产生一个补偿反馈控制信号，在自适应的方式，相应地。 先进的模型预测控制技术将被用来产生控制信号。 此外，优化方法将被用来最大限度地减少热补偿的触觉系统的整体性能的影响。
