Power grid fluctuations are an increasing concern with the high penetration of intermittent generation sources. This paper describes a hierarchical control scheme defined by the dynamics of de-coupled power units over possibly different business domains into an integrated control scheme providing fluctuation mitigation. Specifically, a method built on the combination of charging control of a variable EV fleet and a small-scale energy storage system in a prioritized control hierarchy is investigated with its impacts on both domains. The control hierarchy uses the EV charging dynamics as prime resource for the mitigation of local generation fluctuations and accommodates the residual lack with local electric storage. The definition of a controllable power range for the charging stations allows for the EV charging infrastructure to serve as a power service. The underlying two-layer control algorithms is evaluated through simulations of the dynamics of a residential grid segment combining different grid resources. The results show significantly enhanced performance for effectively reducing the energy surplus-needs through the prime control layer (here: EV charging), but also the need for careful design of secondary power capacities (here: storage).

Flexibility and safety are important criteria for automated material handling systems. Autonomous and decentralized controlled systems are flexible but they also pose new challenges in safety. We describe KARIS, a decentralized controlled, autonomous intralogistic system and indicate the differences to conventional autonomous guided vehicles. Based on the results of a risk assessment, we point out the particular challenges to safety technology and describe the developed safety functions. They are evaluated and compared to required performance levels determined by the risk assessment.

This paper presents an adaptive algorithm to control the position of the linear motor. The algorithm uses the discontinuous fuzzy model of friction with extended functions of consequence in rules. Learning data for tuning the model were collected with using parametric observer for identifying friction. For tuning off-line model, bacterial evolutionary algorithm was used. Adaptive part of the control algorithm was used for the calculation of the friction correction factor. The corrected value of the modeled friction force was used for on-line tuning of fuzzy friction model. The effectiveness of the proposed solution was verified in the real mechatronic system.

This paper introduces a new parallel algorithm called ParDTLT and discusses some of its advantages with respect to a set of well known sequential and parallel algorithms. The parallel process occurs in every node in the decision tree, which is constructed during the supervised training phase. The basis of the distribution of a parallel task is on the attributes of the training objects and the growing of the tree is based on two criteria, who are defined by the maximum number of training objects that every node can support and an entropic gain ratio criterion. Different experiments have been made to compare the behavior of the parallel algorithm ParDTLT with the behavior of the sequential algorithms C4.5, VFDT, YaDT and DTLT and with the parallel algorithm called Synchronous. The experimental results show that ParDTLT keeps the quality of classification and it reduces the execution time.

In this paper, the problem of exponential stability is studied for a class of Markovian jump neutral nonlinear systems with mixed neutral and discrete time delays. By Lyapunov-Krasovskii function approach, a novel mean-square exponential stability criterion is derived for the situation that the system's transition rates are partially or completely accessible. Finally, some numerical examples are provided to illustrate the effectiveness of the proposed methods.

Modern gearless elevator drives have ability to control speed and other parameters of motion like a jerk. Also techniques for indirect vector-control of induction motor provides possibility for efficiency optimization. This paper describes control algorithm based on optimal control. It combines two crucial elements for elevator drive, smooth motion which increase comfort of elevator passengers and minimum energy consumption for one elevator drive. Validity of suggested algorithm is tested through computer simulations.

The problem of designing dynamic output-feedback schemes for a class of linear interconnected continuous-time systems employing networks in the feedback loop is reformulated in this paper as a resilient decentralized delay-dependent feedback stabilization where the subsystems are subjected to convex-bounded parametric uncertainties and additive feedback gain perturbations. Through the construction of appropriate Lyapunov-Krasovskii functional, we characterize resilient decentralized dynamic output-feedback stabilization schemes are designed such that the family of closed-loop feedback subsystems enjoys the delay-dependent asymptotic stability. The decentralized feedback gains are determined by convex optimization over LMIs. The developed results are tested on a representative example.

In this paper, one of the most important problems concerned with the automatic control for marine ships, namely the problem of suppression of external disturbances act on a ship, about which we have no information except its boundedness, is considered. The new method of suppression of bounded disturbances is proposed. The control is sought as a static state feedback. The requirement of the desirable degree of stability is also fulfilled.

A new model reference adaptive control (MRAC) algorithm is presented for a class of nonlinear systems. The proposed MRAC method uses a nonlinear reference model whose controller is designed by using the so-called State Dependent Riccati Equation (SDRE) techniques. The controller designed for the nonlinear reference model is then adapted for the (presumably unknown or uncertain) nonlinear plant dynamics, again by using the SDRE methodology. The proposed methodology is exemplified by using the simulation model of an inverted pendulum, showing the effectiveness of SDRE-based MRAC for nonlinear systems.
