近来，珀耳帖装置作为能够传递热的触觉装置而引起关注，因为其在热装置中具有相对快的响应特性。为了传递热感觉，温度控制被认为是重要的。然而，由于诸如参数变化、装置的非线性特性和从外部物体流动的热等因素，难以设计控制器。此外，最好是跟踪性能和干扰抑制特性独立设计。针对这些因素，本文提出了一种热干扰观测器，它是利用运动控制领域常用的干扰观测器构造的。当观测器被使用时，热系统变得对上述因素具有鲁棒性。另外，可以设计与干扰抑制特性无关的跟踪性能。实验结果证实了该方案的有效性。
Recently, the Peltier device has been attracting attention as a haptic device that can transfer heat, because it has relatively fast response characteristics among thermal devices. To transmit the thermal sensation, temperature control is considered to be important. However, it is difficult to design a controller because of factors such as parameter variations, nonlinear characteristics of the device, and heat that flows from an external object. Moreover, it is preferable that the tracking performance and disturbance suppression characteristics be designed independently.To address these factors, this paper proposes a heat disturbance observer, which is constructed by using the disturbance observer commonly used in the field of motion control. When the observer is used, the thermal system becomes robust to the above-mentioned factors. In addition, it is possible to design the tracking performance independent of the disturbance suppression characteristics. The validity of the proposal is confirmed by experimental results.
