最近，为了增强远程或多媒体通信的真实性，关于被称为触觉的触觉信息传输的研究一直在发展。触觉信息由多个元素组成，例如力感、表面触觉或热感。对于本文关注的热感觉，了解热量流入量非常重要，本文将热量流入定义为从外部流入热器件的热量。通常使用热通量传感器来获取信息。然而，热通量传感器会吸收热量，因为传感器本身具有热电容。结果，在热系统的瞬态状态下，热量流入的信息被改变并且准确的信息没有反馈到控制器。本文提出了一种热流入观测器，它基于扰动观测器来估计热流入信息。通过所提出的方法，将热量流入信息的值反馈给控制器，并且可以控制热量流入。热量流入控制可用于热感觉的传递。进行了多项实验来验证观测器和热流入控制的有效性。
Recently, to enhance the reality of remote or multimedia communication, research about the transmission of tactile information which is called haptics has been developing. Haptic information consists of several elements such as sense of force, surface touch, or thermal sensation. As for the thermal sensation on which this paper focuses, it is important to know the amount of the heat inflow, which is defined in this paper as a heat flowing into a thermal device from outside. A heat flux sensor is generally used for the obtainment of the information. However, the heat flux sensor absorbs the heat because the sensor itself has a thermal capacitance. As a result, in a transient state of the thermal system, the information of heat inflow is altered and the accurate information is not fed back to the controller. This paper proposes a heat inflow observer, which is based on a disturbance observer and estimates the information of heat inflow. By the proposed method, the value of heat inflow information is fed back to the controller, and it is possible to control the heat inflow. The heat inflow control can be used for the transmission of thermal sensation. Several experiments are conducted to see the validity of the observer and the heat inflow control.
