The article presents an approach that compares different municipalities by their energy efficiency level. We propose a clustering of the municipalities by neuro-fuzzy methods to estimate how social, economic and climatic features affect the energy use. The energy use indicators analysis allows to create a set of membership functions in each cluster to get fuzzy measures of energy efficiency. © 2012 IEEE.

The relative pose between inertial and visual sensors equipped in autonomous robots is calibrated in two steps. In the first step, the sensing system is moved along a line, the orientations in the relative pose are computed from at least five corresponding points in the two images captured before and after the movement. In the second step, the translation parameters in the relative pose are obtained with at least two corresponding points in the two images captured before and after one step motion. Experiments are conducted to verify the effectiveness of the proposed method.

In this paper, the research on monitoring and early warning for the loss of consciousness under +Gz accelerations is first introduced. The necessity of research on electroencephalogram (EEG) signal under the condition of +Gz accelerations is then presented. In order to investigate the features of EEG variation in +Gz acceleration environment, experiments are carried out by using high performance human centrifuge. EEG and related physiological signals under different +Gz accelerations are recorded and analyzed by means of periodogram parameters analysis method. The results show that the features of EEG waveform and some frequency bands have obvious change under +Gz accelerations. They also show that the changes of EEG, heart rate and brain blood pressure have different various relevances. The valuable feature changes appeared in advance corresponding to ear pulse level probably have significance on warning syncope induced by +Gz accelerations and can provide important basis for further study. © 2012 IEEE.

The paper focuses on the design of look-ahead control, in which road inclinations, speed limits and traveling time are taken into consideration. In the control system the longitudinal control incorporates the brake and traction forces to achieve the required velocity. The advantage of the method is that during the travel of the vehicle the control calculates the appropriate velocity, with which the number of unnecessary accelerations and brakings and their durations can be significantly reduced. The velocity proposed by the automatic system may interfere with the velocity selected by the driver. In the paper the system based on look-ahead control is compared to a vehicle operated by a driver using a hardware-in-the-loop simulation system. © 2012 IFAC.

The paper focuses on the design of the velocity of a platoon based on fuel consumption, road slopes, emissions and traveling time. Since the performance specifications are in contradiction, the design task leads to a multi-criteria optimization procedure. Moreover, the differences between the dynamics of the vehicles in the platoon should be taken into consideration. The goal of this paper is to develop an optimization method for the velocity of the platoon which creates a balance between the different performance factors. The design of the platoon control is based on the robust H∞ control theory. The method is illustrated through simulation examples, which show that a balance between energy saving, the minimization of traveling time and emission can be obtained. © 2012 IFAC.

The paper proposes a fault-Tolerant integrated control system with the brake and the steering for developing a driver assistance system. The purpose is to design a fault-Tolerant control which is able to guarantee the trajectory tracking and lateral stability of the vehicle against actuator fault *** both actuators affect the lateral dynamics of the vehicle, in the control design a balance and priority between them must be achieved. The method is extended with a fault-Tolerant feature based on a robust LPV method, into which the detected fault information are incorporated. The control design is performed by using the Matlab/Simulink software and the verification of the designed controller is performed by using the CarSim software.

In this paper a multicriteria ramp metering control is designed considering three criteria: traffic performance and the local- and global effects of traffic emission. For realtime emission modeling a macroscopic modeling framework is proposed using an average-speed emission model. Based on the proposed model function cost functions regarding the global and local effects of traffic emission are stated. Traffic control is realized via ramp metering and the control input is optimized by using the NMPC technique. The closed-loop simulation of the designed control is carried out in VISSIM microscopic simulator. © 2012 IFAC.

This paper gives an analysis on the opportunities of using some principles of the hyperbolic geometry in the field of signals and systems theory. Based upon the hyperbolic transform realized by the Blaschke function a hyperbolic metric is defined on the unit circle that corresponds to the notions of the Poincare disc model of the hyperbolic geometry. Based on the hyperbolic metric and the Laguerre representation of analytic functions in the unit disc a method is outlined, which gives the opportunity to derive the poles of the functions. Deriving the poles in combination with function representations in rational orthogonal bases solves the nonparametric identification problem in the frequency domain.

The paper presents a collision mitigation method in which the aim is to stabilize the motion of the vehicle after a light impact has occurred. A yaw rate servo control based on the bicycle model is applied for control purposes. The collision is assumed to have been detected by a passive safety system, e.g., airbag sensors. The control system is activated by the monitoring signal. After the collision has occurred the motion of the vehicle and the operation of the control system are illustrated through CarSim simulation examples. Two control solutions are analyzed: in the first case active steering is used while in the second case steering is combined with differential braking. With the knowledge of certain vehicle parameters and the impact force and direction, post impact vehicle states (yaw rate, velocities, roll rate) can be analyzed. A sensitivity analysis is carried out to determine the validity range of the vehicle model in the presence of uncertainties and different kinds of impact forces. Several software packages are used for the design and analysis of the controlled system. The control design is performed by using the Matlab/Simulink software and the verification of the designed controller is performed by using the CarSim software.

This paper is concerned with the finite-horizon recursive filtering problem for a class of nonlinear time-varying systems with missing measurements. The missing measurements are modeled by a series of mutually independent random variables obeying Bernoulli distributions with possibly different occurrence probabilities. Attention is focused on the design of a recursive filter such that, for the missing measurements, an upper bound for the filtering error covariance is guaranteed and such an upper bound is subsequently minimized by properly designing the filter parameters at each sampling instant. The desired filter parameters are obtained by solving two Riccati-like difference equations that are of a recursive form suitable for online applications. A simulation example is exploited to demonstrate the effectiveness of the proposed filter design scheme. © 2012 IEEE.
