This paper describes the application of Monte Carlo model predictive control (MCMPC) to systems with collision phenomena. In general, a physical quantity related to velocity discontinuously changes at the moment of a collision. Gradient-based model predictive control that requires gradient information of the cost function can not handle the collision phenomena directly. On the other hand, MCMPC can calculate local optimal solutions and stationary solutions needed each time as far as the forward simulation is feasible. Therefore, we examined the problem of swing up and stabilizing the cart type inverted pendulum with the collision of the cart. If the controller can properly handle the discontinuity, faster swing-up may be realized by exploiting impact force caused by the collision of a cart within the evaluation function. In this paper, we show the result of simulations and real experiments, and report that we can realize speeding up of swing-up using collision.

Nowadays shipping industry has problems such as reduction of mariners and aging of mariners. In order to solve the problems, One Person Bridge Operation was developed as navigation supporting system. However, One Person Bridge Operation remained one man error and technological problems. Therefore, in this paper, remote maneuvering between land and ship was proposed by using satellite communication. In this remote maneuvering system, navigation officer works on ship as usual and helmsman supports ship from land. In this study, remote maneuvering system was developed by using satellite communication. For evaluating the remote maneuvering system, ship experiment of remote maneuvering was carried out by navigation officer and helmsman. From the result, navigation officer and helmsman could maneuver a ship accurately between land and ship.

To operate trail running safely while reducing costs, we considered a system that quickly detects participants who are off course or need urgent rescue. The system adopts long short-term memory for the prediction of the trail running participant time.

Vibration power generation utilizing environmental vibrations to generate electricity has been attracting attention as a sustainable independent power source for such as wireless sensors placed under vibration. For efficient power generation, the resonant frequency of the vibration power generation device must be automatically adjusted to the environmental vibrations. To achieve it, the author's group proposes a method of installing a variable capacitance in the device and adjusting its capacitance by extremum seeking control. In the case of damped vibration applied, even if the amplitude and frequency of the vibration vary randomly if their distributions can be regarded as stationary and identical, an effective extremum seeking control method and its effectiveness are demonstrated using experiments.

D-C amplifiers are indispensable for analog computers, measuring instruments and industrial controlequipment.One of major considerations of the amplifiers is the minimum detectable signal which usually issubject to restriction by the drift.With synchronous clamp technique, reduction of the drift can be achieved. This technique is verysimple and yet effective.This paper presents both theoretical and experimental analyses of the effect of synchronous clamp ind-c amplifiers.

Described herein is a transistorized AD/DA Converter which has both analog-to-digital and digital-to-analog conversions.In the analog-to-digital conversion, the instrument accepts 0-5V input voltages with the input impedance higher than 500kΩ and operates on them to produce 0-1000 digital output signal (real out-put is binary coded signal) in 130μ sec with accuracy and precision of 0.1%. The, operation is, of the voltage feedback encoding method.In the digital-to-analog conversion, 0-1000 digital input, signals, are converted into 0--5V output voltages with the equivalent accuracy to that of analog-to-digital conversion. Its output impedance is Iess than 1Ω.The silicon diodes are employed to gate the weighted currents in the DA conversion circuit from which feedback voltages are obtained in the analog -to-digital conversion and the output voltages in digitalto-analog conversion. As all the circuits of the instrument are carefully compensated against the temperature change, it can be used in ambient temperature 5-50°C.
