The Kalman Filter (KF) is a very powerful tool when it comes to controlling noisy systems, because it provides optimal filtering of the noise in measurement and inside the system if the covariance matrices of these noises are known. This paper addresses the study of the KF application to improve the estimation of states through an optimal estimation of the rotor current and proposes a speed control...
Simulations of epidemic spread is an appealing approach to design intervention programs against influenza epidemic. Agent-based approach is particularly useful, since it enable us to administrate and evaluate effectiveness of various intervention measures in the simulated city. On the other hand, observation date are obtained as macroscopic information. Hence, we need to extract some macroscopic information,...
The estimation of many unknown parameters is carried out using a simplified Sequential Importance Sampling (SIS) algorithm which is implemented in a graphic processing unit (GPU). The aim of the present work is to show technical points to bring out the performance of GPU. Using the implemented code, two numerical experiments are demonstrated. In the first demonstration, it is shown that a parameter...
This paper describes the assist force control of semi-active assist system ldquosmart suitrdquo for horse trainer. We developed a soft and flexible power assist device named ldquosmart suitrdquo for reducing horse trainers' physical fatigue in their horse training works in order to prevent their spine or legs injuries. The smart suit is a kind of semi-active and flexible power assist devices. In order...
This paper deals with a three-phase to single-phase power conversion system using a matrix converter topology. In order to compensate for instantaneous power unbalance occurring between three-phase circuits and single-phase circuits, a small reactor is installed into a matrix converter. The proposed circuit and control diagrams as well as some important simulation results are described herein.
Backlash mechanisms can be seen in many mechanical systems and they may deteriorate the performance of the systems. So the control of the backlash is very important for practical applications. In this paper we propose a control method for a simplified transmission system with the backlash using a Model Predictive Control (MPC) and Unscented Kalman filter(UKF). The efficiency of the proposed method...
