By applying rotor angle sensorless control methods the costs of electrical drive can be decreased while its reliability is increased. Traditionally, design both estimator and controller require a detailed motor model manual tuning leading to significant effort by human experts. In this work, anisotropy-based scheme for interior permanent magnet synchronous motors (IPMSM) proposed that enables w...

As the workforce becomes increasingly diverse, motivating individuals from different backgrounds to work together effectively is a major challenge facing organizations. In an experiment conducted at a large public university in the United States, we manipulate the salience of participants’ multidimensional natural identities and investigate the effects of identity on coordination and cooperatio...

Guidance and control of aircraft in the landing phase imposes extra pilot work loads, hence application of automatic landing control systems is of great importance. In this study automatic landing control systems are introduced and an optimal landing control system is designed. The control system performance criteria are based on minimum control effort. The designed system is simulated for a tr...

Minimum-process coordinated checkpointing is a suitable approach to introduce fault tolerance in mobile distributed systems transparently. It may require blocking of processes, extra synchronization messages or taking some useless checkpoints. Allprocess checkpointing may lead to exceedingly high checkpointing overhead. To optimize both matrices, the checkpointing overhead and the loss of compu...

This paper deals with the problem of best effort traffic delivery in 802.11e contention-based networks. Differently from most previous paper which focus on the support of quality of service (QoS) requirements, we study the tuning of the access parameters for the best effort traffic. The contribution of this paper is threefold. First, we discuss the coexistence between legacy DCF and EDCA statio...

An optimal strategy based on minimum effort control and also with terminal positionconstraint is developed for an exoatmospheric interceptor with a fixed- interval guidance time. It isthen integrated with sliding-mode control theory to drive an optimal sliding-mode guidance law forfixed-interval guidance time. In addition, this guidance law is generalized for intercepting anarbitrarily time-var...

Using a computational testbed, we theoretically predict and experimentally show that in the minimum effort coordination game, as the cost of effort increases, 1) the game converges to lower effort levels, 2) the convergence speed increases, and 3) the average payoff is not monotonically decreasing. In fact, the average profit is an U-shaped curve as a function of cost. Therefore, contrary to th...

In this paper, we investigate opportunities to improve the performance of minimum effort driven faceted search techniques. The main idea is motivated by the early stopping techniques used in the TA-family of algorithms for top-k computations. Our initial set of experimental results demonstrate that the proposed techniques expedite performance significantly.

We consider the problem of characterizing a spatial partition of the position space of a team of vehicles with linear time-varying kinematics. The generalized metric that determines the proximity relations between the vehicles and an arbitrary target point in the partition space is the minimum control effort required for each vehicle to reach the latter point with zero miss distance and exactly...
