キーワード : T-S fuzzy model，State observer，disturbance observer，LMIs，Separation property，System stability
Regarding the T-S fuzzy model as a mathematical model of the plant to be controlled, the model is widely used in the fuzzy control systems for the purpose of designing controller. In this paper, the so-called lumped dist ... more
In recent years, the manufacturing industry has seen a shift of the domain of competition from “performance” which can easily be expressed numerically to “design” which is hard to be expressed numerically. The rise of co ... more
Inverse Reinforcement Learning (IRL) is a promising framework for estimating a reward function under given behaviors of the expert. However, the IRL problem is ill-posed in that several reward functions that can reproduc ... more
We propose server and storage resource partition method for mission critical system consolidation to prevent performance interference in cloud computing environment. We made experiments to allocate dedicated CPU core and ... more
Verification of the Effectiveness of Price Presentation Considering Consumer's Purchasing Behavior by Smartphone Application for Reducing Food Waste Disposal
In recent years, food waste disposal, food loss has become a social problem. Among them, attention is focused on reducing food loss. Food loss refers to the disposal of parts that were originally available for eating dur ... more
In IoT (Internet of Things) systems, sensors and actuators placed in the data generation site are connected to the cloud via a network, and operations such as data transmission, analysis, and feedback are handled without ... more
Since solar power generation has increased rapidly, balancing function, especially in the form of increasing demand, is becoming needed. We propose technique of demand response in which an aggregator dispatches home appl ... more
A compact rat-race circuit consisting of planar circuits is presented in this paper. The prototype is fabricated at 1GHz, and the propagation characteristics and reflection characteristics of each port are measured. The ... more
In this paper, efforts of transfer skills in traditional crafts are introduced. A case example of a skill analysis of a paper making craftsman among traditional crafts is shown. Motion capture system measures the differe ... more
In 2011, the Ministry of Education, Culture, Sports, Science and Technology showed a comprehensive promotion policy "Information vision of education" on information education for fiscal 2020. It is necessary to research ... more
PID control is widely applicable in industrial field because of few control parameters and comprehensibility of physical meaning of control input. Moreover, experience and intuition of veteran engineers are needed to aim ... more
Since a decrease in muscle mass of elderly people, the physical burden of them in standing-sitting motion of a seat are increasing than young people. For this problem, several standing-sitting support systems have been d ... more
In the control education, students are able to understand the control theory intuitively through the education using experiments. In this study, the authors develop an experimental device for the control education. By us ... more
In process Industries, there is a growing trend toward low carbon society. Especially in oil refinement and petrochemical industries, furnaces consume a lot of energy. In order to reduce the energy consumption, excess O2 ... more
