Three converter leg variants are analyzed for low power converter used for power electronic system for residential buildings. The two-level Si-IGBT and SiC-MOSFET converters are compared with Si-IGBT three-level T-type converter. Power losses generated in each of these converters over a predicted period of 20 years of operation are contrasted with the cost of converter options. The detailed selection procedure for output inductor is presented in this paper. This procedure shows the influence of the inductor parameters like number of turns, air gap length on its losses, cost and size. Theoretical approach is verified with simulations and experimental results.

Major construction and initial-phase operation of a second-generation gravitational-wave detector KAGRA has been completed. The entire 3-km detector is installed underground in a mine in order to be isolated from background seismic vibrations on the surface. This allows us to achieve a good sensitivity at low frequencies and high stability of the detector. Bare-bones equipment for the interferometer operation has been installed and the first test run was accomplished in March and April of 2016 with a rather simple configuration. The initial configuration of KAGRA is named iKAGRA. In this paper, we summarize the construction of KAGRA, including the study of the advantages and challenges of building an underground detector and the operation of the iKAGRA interferometer together with the geophysics interferometer that has been constructed in the same tunnel.

This paper addresses to the problem of designing, modeling and practical realization of robust model predictive control for finite and infinite prediction horizon which ensures a parameter dependent quadratic stability and guaranteed cost for linear polytopic uncertain systems. The model predictive controller design procedure based on BMI and LMI is reduced to off-line output feedback gain calculation. A numerical examples and an application to a real process is given to illustrate the effectiveness of the proposed method.

The paper deals with the robust controller design using conventional approaches (Small Gain Theory, Equivalent Subsystems Method), and advanced robust genetic method for uncertain MIMO systems. Decentralised robust controllers designed using the Small Gain Theory (SGT) ensure robust stability for additive, input/output multiplicative uncertainties; the Equivalent Subsystems Method (ESM) guarantees the required performance in terms of phase margin and settling time for input/output multiplicative uncertainties. The genetic algorithm is based on optimisation procedure, where the cost function to be minimized comprises the closed-loop simulation of the controlled MIMO process and evaluation of a selected performance index. Using this approach, the PID controller parameters were optimised to obtain the required behaviour of the controller process. Practical implementation and comparison of the proposed methods are verified and tested on a real process - two interconnected DC motors with varying parameters.

In this paper, we introduce a decentralized event-triggered scheduling scheme for multi-loop Networked control Systems (NCSs) in which the individual control loops are coupled through a shared communication channel. The proposed scheduling design combines deterministic and probabilistic attributes to efficiently allocate the limited communication resource among the control loops in an event-based fashion. Based on local error thresholds, each control loop determines whether to compete for the channel access. As a result, control loops with higher transmission priorities are more likely to utilize the channel, which in turn leads to more efficient usage of the limited resource. Each eligible subsystem then attempts to transmit at times specified by local waiting times, which are randomly distributed and local-error dependent. In this manner, the probability of data collisions in the communication channel is reduced. If the channel capacity is reached at some time instants, data packets are dropped. We demonstrate stochastic stability of such NCSs in terms of Lyapunov Stability in Probability (LSP). The numerical results show that our approach improves resource utilization and reduces the networked-induced error variance in comparison with time-triggered, random access, and centralized scheduling policies.

IEEE International Conference on Automation Science and engineering (CASE)

作者： Ulrike Thomas Theodoros Stouraitis Maximo A. Roa Faculty of Electrical Engineering and Information Technology Technical University of Chemnitz Germany Institute of Robotics and Mechatronics German Aerospace Center Germany

This paper describes an assembly sequence planner able to generate feasible sequences for building a desired assembly. The assembly planner takes geometrical, physical and mechanical constraints into account. Moreover, the planner considers the feasibility of grasps during the planning process and takes into account work-cell specific constraints. The approach uses AND/OR-graphs for planning. The generation of such graphs is implemented by using a specialized graph cut algorithm that employs a dynamically changing priority queue. These graphs are further evaluated by considering the feasibility of grasping sub-assemblies and individual parts during the process. The grasp and the sequence planner are generic, hence the proposed solution can be applied to arbitrary assemblies of rigid parts. The system has been evaluated with different configurations obtained by the combination of standard item-profiles.

Multiple mechanical systems are vulnerable for oscillations. Its occurrence is very unwanted in systems. The Input Shaping method might be used for control the object without of oscillations stimulation. The fuzzy logic control might be used, when the information about object are not well known or uncertain. Usually this kind of control grants proper work of whole system. The common work of both proposed algorithm is different from classical control using regulator and input shaping. The nonlinearities in fuzzy controller excludes usage classical methods of input shaping. Two other structures are prepared, tested and presented in paper. All research was made in Matlab/Simulink.

We present a new technique for the synthesis of a robust model predictive controller with infinite prediction horizon. The proposed controller design approach ensures a parameter-dependent quadratic stability and guaranteed cost for linear polytopic uncertain systems. The proposed design procedure based on BMI or LMI reduces to off-line output feedback controller gain calculation minimizing an upper bound on the “worst case” an objective function. For the case of our approach and input (output) constraints at each sample time step for each input (output) scalar parameter is calculated, which radically decreases the computational load. The controller design is illustrated by examples.

Method for detecting the isomeric state I=(3/2)+ in Th229 with laser-induced fluorescence

引用

Physical Review A 2015年第1期92卷 012519-012519页

作者： J. Dembczyński M. Elantkowska J. Ruczkowski Institute of Control and Information Engineering Faculty of Electrical Engineering Poznan University of Technology Piotrowo 3A 60-965 Poznan Poland Laboratory of Quantum Engineering and Metrology Faculty of Technical Physics Poznan University of Technology Piotrowo 3 60-965 Poznan Poland

There are different predictions regarding the position of the isomeric state of Th229m. There is some question as to whether it even exists. We propose simple experiments to provide the evidence of the existence of this isomeric state. If the metastable isomeric state exists, we should be able to observe the effects of mixing of the nuclear wave functions of the ground state I=5/2 and the isomeric I=3/2 state via electronic shells. It will be shown as the differences between the hyperfine A and B constants, which will be measured by means of the laser-induced fluorescence methods and those predicted by semiempirical calculations. The wave function for the atomic state |***〉 contains contributions from both nuclear states I=5/2 and 3/2, thus its effects on the hyperfine-structure patterns of spectral lines should be observed, confirming the existence of this isomeric state.
