The Inverted Pendulum is the benchmark system for control methods. Most linear controllers are not efficient under the situations of disturbances and other uncertainties. As high precision and robustness are required, a sliding mode controller is used in this work. Due to uncertainties, a model free based observer is used to estimate some states. The simulation and real experiment results demonstrate the robustness of the controller and the efficiency of a model free observer.

Poly-N-isopropylacrylamide (poly-NIPAAM) has been widely used in tissue engineering and micro-structure in micro-fluidic applications. Generally, NIPAAM is polymerized and patterned by a conventional UV irradiation or UV lithography. This paper proposes a photo-polymerization method of NIPAAM using UV LED microscope. Through the combination of a commercialized UV LED, optical components, an objective lens and X-Y-Z motorized stage, we fabricated a UV LED microscope for the photo-polymerization of NIPAAM. In addition, for the investigation of the polymerization procedure, CCD camera and an illumination light source using red LED and optical components were installed. For the polymerization of NIPAAM solution, a simple micro-fluidic channel was fabricated and the NIPAAM base solution was injected into the micro-fluidic channel. If the UV LED beam was focused on the channel with NIPAAM solution, the NIPAAM can be polymerized in the focused region. Finally, we can directly fabricate micro-structures of poly-NIPAAM by using the proposed UV LED microscope.

RoboCup Rescue constructs a virtual agent-rescue disaster environment with buildings burning, roads blocked, and civilians in injure. Due to the tricky tasks of building inferno control in this simulation platform, this paper presents a temperature and fire spot prediction model based on the grey system theory. Rather than the previous way that just extinguishing burning buildings, a pre-extinguish method which is much more efficient in the process of controlling fire spreading by handling not-burning buildings is applied here according to the prediction model, in which the building temperature of the next cycle can be estimated so that whether the building is about to catch fire will be foreknown and advanced decisions will be exploited by agents. Experimental results show that this method can achieve an enhanced effect during fire control process of the fire brigade agent in RoboCup Rescue competitions.

In ocean thermal energy conversion (OTEC) plant, electricity is generated by heat energy from temperature difference between warm seawater at surface and cold seawater in depth. OTEC plants have an evaporator as one of the most important devices. Indeed, the evaporator evaporates the working fluid to rotate the turbine connected to the generator. In this research, a model of heat source system in an OTEC pilot plant for stable operation of the plant is constructed. In the OTEC pilot plant, the evaporation of the working fluid is realized by warm water from a boiler. Therefore, it is important to keep the temperature of warm water constant. Since the temperature of warm water can be changed by manipulating the valve opening, first order models to describe the relationship between the temperature and the valve opening are constructed based on experimental data. The effectiveness of the constructed models was verified through simulation.

The conventional screw propeller is widely used for ships and water vehicles. However, the screw propeller has safety problems that get entangled in the fish net or the algae. In addition, the propulsion by the screw consumes a lot of energy. The goal of our research is the development of an alternative propulsion method for the unmanned surface vehicle to the screw propeller. In this paper, we focus on the gliding locomotion which is defined as the forward motion by the difference of the friction between the normal direction and the tangential direction. In particular, we have considered a mechanism of the surface vehicle propulsion with the gliding locomotion using only single servo motor. Moreover, we have developed a model vehicle with the proposed propulsion which can drive forward and gyrate. Then, we have shown experimental result and consider the performance.

In this paper, the Continuous Motion (CM) NCTF controller is proposed for a point-to-point (PTP) positioning system of a one mass rotary system. For this system, the CM-NCTF controller is designed based on the conventional structure of NCTF controller and improved. The CM-NCTF controller consists of Nominal Characteristic Trajectory (NCT) and Proportional Integral (PI) compensator. It is designed without knowing exact system modeling and parameter evaluation. The NCT is constructed from open loop responses while the PI compensator is designed based on the constructed-NCT itself. The effectiveness of the CM NCTF controller is evaluated and compared with the PID controller for positioning and tracking motion performances experimentally. The robustness of the CM NCTF controller is validated by varying the mass load. Overall, the CM-NCTF controller demonstrates promising positioning and tracking performances, and low sensitivity towards the change of mass load in comparison with the PID controller.

We are developing a small compact electric motor tricycle with a low powered battery (7.2 V, approximately 2Ah in total) as the electric power source for shopping purposes. The reduction ratio should be adjusted per the driving situation because of the use of a low powered battery. We designed an actuator system with speed change mechanism for the compact electric motor tricycle. A consumer bicycle is used as the base vehicle, and we focused on the development of an actuator system. A multistep transmission mechanism was designed and fabricated using gears, chains, and sprockets. A 150 W maxon DC motor was used, and the motor speed was controlled using a PWM using MOS-FETs and a PIC microcomputer. Running experiments were conducted to observe the performance of the fabricated vehicle. We confirmed that the fabricated vehicle was able to operate over 30 minutes at a speed of over 3 km/h. Longer running duration must be addressed in future research.

The primary function of train control system prevents train collisions by keeping the safe interval with the preceding train. The train control system is consisted of wayside and onboard equipment. The wayside train control system generates control information necessary for train operation, and the onboard train control system controls operational conditions of vehicle and train speeds through information transmitted from the wayside. To improve practical usability in the business area, the safety analysis and evaluation of train control system are needed. In this paper, we design train control simulator for communication based train control system to evaluate the design of train control and operation. The paper presents the simulation configuration, and designed modules and those operations.

This paper deals with a flying observation which are consist of a helium gas balloon and a tilt rotor helicopter. The helium gas balloon can make flight for a long time. The tilt rotor helicopter is stable in the wind and increase buoyant force. The observation system with the helium gas balloon and the tilt rotor gets the best of both worlds. In general, helium gas is released from a balloon in every aerial photographing work. Moreover most aerial photographers with the balloon give up a flight in the wind of 5 m/s or greater. However proposed device does not need to release helium gas. Additionally, the flying observation device in the proposed can make a flight in the winds of 5 m/s or greater.

This paper presents a robust T-S Fuzzy controller with a weighted integral action for Permanent Magnet Synchronous Motor which have nonlinear dynamics. The T-S Fuzzy controller is used for the robustness of nonlinear systems and the weighted integral action is used for the improvement of control performance. A T-S Fuzzy controller is designed by combining the local controllers with the overall stability, and LMI(Linear Matrix Inequality)is used to determine the gains of linear controllers. The control performance of PMSM is changed into regulator problem by introducing the integral action and the weighting factor gives flexibility to a T-S fuzzy controller.
