In this paper, we define the concept of linguistic variable with interval confidence level (LVICL) and some operational laws of LVICLs. Based on these operational laws, we propose some new aggregation operators, such as the interval confidence linguistic weighted arithmetic averaging (ICLWAA) operator, interval confidence linguistic ordered weighted averaging (ICLOWA) operator and interval confidence linguistic hybrid aggregation (ICLHA) operator. Furthermore, based on the ICLWAA and ICLHA operator, we develop a group decision making approach, in which the criteria values take the form of LVICLs and the criterion weight information is known completely. Finally, an example is given to illustrate the effectiveness and feasibility of the developed method.

In prediction error method, it is known that the sequence of the criterion function converges uniformly in the parameter with probability one as the length of the input-output data tends to infinity. When the minimizing points of the limiting function criterion are not unique, the convergence of parameter estimation is not guaranteed in general. Two cases are distinguished. The case one is that the set of the minimizing points of the limiting function criterion is a continuum, and the case two is that the points of that set are isolated. Some interesting phenomena relating to the different cases are shown about the asymptotical behavior of parameter estimation through examples and theoretical analysis.

This paper designs a MCU-based robot fish with caudal fin in order to model the robot fish and verify the related control methods. Firstly, this paper presents an overall design according to the functions required and then chooses the ideal servo motor after calculating its parameters based on the amplitude and frequency of the sine law. In addition, the controller, the inertial navigation model, the wireless communication model, the power supply, the electric circuit and the shell is designed and implemented considering of the limitation of the speed, interface, and cost and so on. In the software design, this paper solves the problem that the MCU is inefficient on the calculation of the float with the method of looking up the sine table, so that the SPWM wave drives the servo motor smoothly. With the program of IIC and SPI bus on the MCU and the control program based on Labview on PC, this paper realizes the wireless communication between the robot fish and PC, making the data collection and remote control possible. In the last, the robot fish is tested.

Mobile non-holonomic robot motion control with collision avoidance is investigated in this paper for the case of unknown concave obstacles locally sensed. Motion control achieves in this case a reactive motion using velocity potential fields approach in a modified, quasi-harmonic, solution. Analytical solutions and simulations show how the harmonic solution for collision avoidance with concave obstacles can be separated smoothly from a non-harmonic solution for positioning.

The main contribution of this paper is the development of hybrid model predictive control and fault detection strategy for wind energy conversion system (WECS) based on mixed logic dynamic (MLD) model framework. The MLD model for WECS including multiple work regions is established. Also the hybrid model predictive control method based on the MLD model of WECS is adopted to implement the variable speed constant frequency control and variable pitch control for the optimal power tracking. The mixed logic dynamic fault (MLDF) model is also established for generator speed sensor fault and the pitch actuator fault of WECS. Moving horizon estimation (MHE) method is applied to estimate the fault states of WECS based on MLDF model of WECS. The performance and the efficiency of the proposed approaches validated via simulations.

Building energy consumption and human comfort are two major but often contradictory themes in modern building management. To alleviate the contradiction between the two themes, multi-objective optimization methods are always introduced. In this paper, three indexes, thermal comfort, visual comfort and indoor air quality (IAQ) are integrated to evaluate the indoor comfort. Based on a multi-agent structure, a model including comfort function and energy function is proposed. The multi-objective genetic algorithm is used to optimize the energy and comfort targets. And the Pareto optimal solution and its sensitivity analysis are discussed under several cases.

In this paper, autonomous target localization is achieved on quadrotor helicopter, with the use of 2D laser rangefinder and fixed monocular camera. Color-featured target is located in 3D space without prior knowledge of its size or shape. Coordinate systems of camera and laser rangefinder are integrated to establish body-fixed reference coordinate system for both localization and flight control. Rotation compensation algorithm is developed to neutralize the errors introduced by the changes of attitude angles during the flight. With this feature, quadrotor can obtain the real world coordinates of target from one single frame of camera once the target is captured and identified, without the requirement of keeping orientated towards the target all the time. The relative position between quadrotor and target is updated every time the target is located. Indoor experiments are conducted with Asctec Pelican quadrotor to demonstrate the performance of the proposed localization approach.

The kinematic model of carrier-based aircraft was established. The airwake model described in USA military standard was introduced and analyzed. A landing simulation system was build based on the kinematic model of aircraft and airwake model. Numerical simulation was carried out to research the effect that airwake acted on the flight performance of carrier-base aircraft. Simulation results show that the gliding track of aircraft affected by airwake is lower than reference gliding track, which reduces the landing safety. The random component and free-air turbulence component of airwake own the dominate part of effect, the steady component makes contribution too, the periodic component acts little effect on aircraft. Airwake affects flight performance of aircraft by putting effect on the aerodynamic force of aircraft but not aero dynamical moment.

For the multiple extended target tracking (METT), one crucial problem is how to partition the measurement sets accurately and rapidly. Due to the disturbance of clutter, the conventional methods, such as distance partition method, K-means++ method, etc., cannot give a perfect partition. In this paper, a novel partition method is proposed based on density analysis and spectral clustering technique. Firstly, construct the density distribution function of the measurements by using the Gaussian kernel, and then eliminate the clutter from the measurements. Secondly, the spectral clustering technique based on neighbor propagation is introduced to partition the measurements. Finally, the Gaussian mixture probability hypothesis density method is used to achieve the METT. Simulation results show that the proposed algorithm has a better performance, especially a better real-time performance, than the conventional methods.
