This paper establishes three models of dynamic input-out economic systems with multiple delays. Uncommonly, the systems are with probably singular capital coefficient matrices which are greatly common in practical economic models. By equivalent transformation, the economic models are written as three discrete-time singular systems with multiple delays. Furthermore, three admissibility conditions are presented and expressed in terms of linear matrix inequalities (LMIs) by Lyapunov approach respectively.

The aim of this paper is to control the position of two balls in interconnected vertical tubes using two dc fans, ultrasonic sensors and computerized controller. A comparison of different kinds of controllers is performed to find the best adjustment. Indeed, by controlling the speed of a fan that pumps the air toward a ball, the air pressure under the ball will be adjusted such that it suspends the ball in the desired position and hold it in that height. Firstly, required hardware that includes mechanical and electrical parts, is designed and implemented, then an appropriate controller is designed in MATLAB and connected to sensors and actuators via interfaces. The used controllers, are PID and sliding mode controller where sliding mode controller led to better results.

The fault estimations problem for networked control systems with signal quantization is considered. With the logarithmic quantizer consideration, the recently developed Generalized Kalman-Yakubovich-Popov (GKYP) Lemma is exploited to formulate the quantized fault estimation filter design problem in finite frequency domain. The quantzied measurement signals are dealt with by utilizing the sector bound method, in which the quantization error is treated as sector-bounded uncertainty. LMI-based conditions are given to design the quantized filter to make the error between residual and fault as small as possible despite of the disturbance effects and quantization errors. And a numerical example is given to illustrate the effectiveness of the proposed method.

In this paper, a new 5-DOF spacecraft simulator which is a frictionless environment simulation platform is described. The simulator has two translational degrees of freedom and three rotational degrees of freedom. It is used for experimental validation of various spacecraft control strategies on the ground. A set of three inertial wheels and a set of sixteen cold-gas thrusters are used as primary actuators for attitude and position control. A ceiling-mounted camera is used to measure the attitude and position of the simulator. The implementation of the attitude and position control algorithms is done on-board using a PC104. Also, an automatic balancing system is developed to eliminate gravity disturbance torque. Finally, an attitude control experimental results is presented.

This paper concerns the finite-time stabilization of discrete Markov jumps systems (MJSs) with partly known transition probabilities (TPs) which are allowed to be known, uncertain with known lower and upper bounds and completely unknown. Combining the property of TPs, sufficient conditions are developed to guarantee that the system states do not exceed a certain threshold in mean-square sense during a specified time interval. It is shown that the method proposed in this paper is less or at least the same conservative than the existing result. Numerical examples are further given to demonstrate the effectiveness of the proposed method.

Despite the fact that current device works significantly well on the utilization of geothermal, the management is still extensive and relies on human experiences mainly. For such reasons, the device parameters cannot be flexible enough to make full advantage of the device and the geothermal cannot be fully utilized. To solve this problem, this paper analyzes and compares some existing expert system based on their different knowledge, and summarizes the knowledge representation, common reasoning strategies, key issues such as forward chain, backward chain of the expert system and finally illustrates a practical and feasible automatic monitoring system of the step utilization of deep geothermal well based on expert systems.

In this paper, a robust L2-L∞ filter design method is presented for a class of continuous-time uncertain nonlinear systems of which the output equations contain the time-varying delay and the saturation items while the state equations contain the time-varying delay items. The memoryless sector region method is utilized to deal with the saturation, and the nonlinearity is subjected to the Lipschitz condition. A delay-dependent Lyapunov-Krasovskii functional(LKF) approach is presented to guarantee that the filtering error system is asymptotically stable and satisfies the L2-L∞ performance constraint. An illustrative example is used to elucidate the efficacy of the proposed approach.

Some systems suffer from not only input saturation but also input rate saturation due to special need or actuator limitation. This paper investigates the regulation control of a class of uncertain nonlinear systems with input rate saturation. By transformation, the rate saturation of input can be converted to the state and input constraints of certain linear systems. An LMI based method can then be introduced and improved to solve the transformed problem. The optimized state-feedback controller is robust to parametric uncertainties. It can guarantee the exponential stability of the original system without external disturbances, and can make the state trajectories exponentially converge to a defined region with external disturbances. Simulation results are presented to demonstrate the effectiveness of the proposed control scheme.

As is known to all that more and more sub-health problems have been induced by weight concerns. Due to the universality and the popularity of Android Smart Phone in the domestic and foreign markets, it is possible for us to develop a real-time weight management APP software based on Android Smart phones. Working out a kind of smart insole with a wireless communication module is also necessary for the success of data transmission and data processing through the sensor in the insoles. Such a system can identify the current state of bodies' weight and sitting posture according to the plantar pressure station and will remind the users to stand up and move around to avoid a long-term sitting. It has been pointed out that this kind of system has its own profound and practical significance for the application of Smart phones in the health management.
