We propose a combined control technique of PID control and disturbance observer for the temperature control of a deionized (DI) water heater that has the structure of a serial process. The results of both simulation and actual equipment experiment verify that the proposed method enables us not only to use fewer temperature sensors than the conventional system but also to solve the offset problem that is typical for the serial processes.

Behaviors, poles, zeros, stability, controllability, observability, transfer function, and other traditional concepts are discussed mainly besed on the Willems' behavioral approach. Moreover the extensions to LQ optimal control problem and computation of Hoc norm are investigated.

This lighting control system makes the desk area that a person uses brighter, but makes the lighting gradually dimmer with distance from the person at a desk. In addition, the air-conditioning system controls temperatures only for areas where someone is at the desk, which can be done by controlling the on and off time of the thermostat in the air-conditioning system. We evaluated this control system by actual measurement and simulations and validated its effectiveness for the reduction of electrical power consumption.

With IoT systems, several technologies must be combined systematically. Design and construction of IoT systems require great amounts of knowledge, time, and funds. In this paper, we propose a method of prototype construction for the active creation of IoT application ideas. This method clearly presents contents and procedures for prototyping for students of non-IT courses and non-science/non-engineering courses in their own specialized fields. This method has an IoT device implementation framework. Application of the framework facilitates ease of connection of versatile sensors and actuators. After the prototype is constructed according to this construction method, those who constructed it (constructors) can perform problem solving, idea creation, and needs assessment related to their own specialized fields. This construction method was applied practically by science and engineering students in non-IT courses and non-science/non-engineering students, for whom its effects were evaluated.

Prototyping of M2M / IoT systems is an effective way to embody the idea on the systems and to examine their feasibility. This paper describes a method for prototyping of M2M / IoT systems, which consists of how to embody the idea of them, how to select their components and how to build them using a framework, so that people can easily construct M2M / IoT systems to solve their problems. This paper also describes three different applications of this method, which proves its effectiveness.

Dynamic characteristics of the slider-crank mechanism significantly changes depending on the wheel rotational angle. Thus, to achieve a good control performance, it is necessary for the plant parameters to be identified at the each section divided into six by the wheel angle. This kind of control based on the local modeling is useful not only for such a slider-crank mechanism but also for highly-accurate positioning control systems with significant nonlinearity. The validity of the proposed method is verified through simulations and experiments.

In this paper, a formulation of dissipativity for linear time-invariant system on pencil model is derived. According to the structural properties of canonical form for pencils, it can be shown that a storage function is written as a quadratic form of the solution of the LMI which consists of the original system parameters.

Especially force communication is a hopeful application in the coming e-world. Bilateral tele-operation system is a kind of technology utilize for the application. But it is well-known that the computer network has inevitable time-delay ami jitter in the transmission of the data, and which deteriorates the stability and performance of the systems. In this article previous researches for the problem are reviewed and a robust control system with no force sensor is proposed.

We proposed combined control technique of PID control and disturbance observer for the temperature control of deionized (DI) water heater that is used for semiconductor processing equipment. The result of both simulation and actual equipment experiment verified that the proposed method enabled not only to use fewer temperature sensors than conventional system that leads to a cost reduction but also to have robustness against model uncertainty of a lamp heater such as a nonlinearity of input-output relationship, power variation, and sudden burnout.
