We present interactive learning tools for the education in classical automatic control. The tools are aimed at improving the understanding of and skills for analysis and design of control systems. The tools are implemented in MATLAB and can be used via the Internet. The tools are enhanced by detailed helps and hints and can be used by the students for solving seminar problems and individual learning. They can be implemented as a teaching aid during the lectures in classical automatic control, as well. Both, Japanese and English versions of the tools are developed.

The intelligent controls such as a neural network based control for mechatronic positioning servo systems have been researched actively in recent years because the mechanism design could not cope with the advanced requirements. This paper proposes a novel robust fuzzy-neural network based control for the mechatronic positioning servo systems that have nonlinear characteristics such as friction, backlash, variations of load and system parameters, and unknown disturbances. Computational simulation results for one-degree-of-freedom positioning system are shown to confirm the validity of the proposed controller.

Presents a design method of a decentralized controller for large scale linear interconnected systems using an interaction model. An aggregated model that reflects the real interaction is considered as an interaction model. A sufficient condition for the total system to be stable is presented relating to the interconnections among sub-systems, when the total system is controlled via each local feedback controller proposed here using the available information.

In this paper, we expand the linear prediction method of Chan et al. (1981) in the case where the number of the frequency components in the signal is unknown. In the proposed method, we assume an unknown number J is larger than the number of the frequency components in the signal, by using J, the exact frequency components in the signal can be estimated.

Advanced aircraft such as a control configured vehicle (CCV) provide the capability to control the aircraft in unconventional ways. One such approach is to generate decoupled motions, which can be used to improve tracking and accuracy by using eigenstructure assignment. However, generally, the robustness of eigenstructure assignment is not satisfactory under parameter uncertainty. In order to keep the high performance requirements under the undesirable situations, an indirect adaptive control using eigenstructure assignment is proposed. An example of a simple model is presented to illustrate the usefulness of the proposed algorithm and confirms the possibility of extension into flight control problems.

We present a frequency estimation method of acoustic signals based on the sinusoidal additive synthesis model. In the proposed method, frequencies both in signal and noise are estimated with several delay times by using an extended LP method. Performance of the proposed method is evaluated by computer simulation, and the lower variance of parameter estimation error is estimated by using the Cramer-Rao bound.

We have developed an algorithm by attaching the camera to the end-effector of an industrial 6 axis robot which determines position and orientation of the camera system from cartesian coordinate. When the camera is attached to the end-effector of an industrial robot with a calibration mask that has more than 8 points, it has been proved that it is possible to determine the position and orientation of the camera system even without special measuring equipment.

Presents a method for rotor position detection and speed estimation of permanent magnet synchronous machines. Information is obtained by monitoring controller signals to eliminate position and speed sensors. A drive system model is developed for a free running machine and sensorless vector control operation then simulation is carried out to verify effectiveness of the proposed method. The method can reduce the system cost and improve the drive system reliability.

We have examined the particle size measuring method in which flour particles are floated into the airflow at a test section with its upward velocity equal to their terminal velocity. As a result, it was verified that the terminal velocity was experimentally related to the size of floating particle, and that it made possible to obtain spherically equivalent diameter of the floating particle by an elliptical approximation of the image. We further applied this floating method to measure particle size distribution as a simpler way in which the floating particles were counted in number according to the various upward velocities.

Kwon et al. (1989) derived a recursive adjoint form of FIR filter and smoother for discrete-time state-space models. Even though it is algebraically identical to the FIR filter and the FIR smoother, unfortunately it is pointed out to be numerically unstable. This makes the recursive estimator (RFIR) seldomly used in real applications. So we have devised a stable recursive estimator (SRFIR) which can supplement the RFIR so that it could be stabilized, and show that the SRFIR has unbiased and minimum variance error.
