The TCP congestion control plus RED queue management can be modeled as a discrete-time dynamical system, which can create complex bifurcating and chaotic behavior. Based on the model, we propose a time-dependent delayed feedback control method for controlling chaos in Internet congestion control system, and an adaptive parameter-tuning algorithms are proposed. Numerical examples show that the average queue length in the buffer of the router can be stabilized at the fixed point in the originally system.

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.

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.

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.

Cloud computing is becoming an important and popular platform of service computing for supporting on-demand service sharing in the large-scale distributed systems. One of the difficult challenges in cloud computing is how to deliver the reliable web service composition over unreliable web services around the world. To improve the automated diagnosis capability for service composition in cloud, we present diagnosis architecture and a log-based diagnosis method. By decoupling diagnosis service to share diagnosis resources, our diagnosis architecture could select an optimal diagnosis service according to the faulty type. By converting the successful activity execution logs into the diagnosis model, our diagnosis method can identify the faulty activities based on the differences between correct and observation execution traces. Case study shows that our method is effective in diagnosing service faults in cloud.

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.

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.

This paper investigates the dynamical consensus problem of second-order multi-agent systems subject to Markov jumping delays. In this study, agents not only collaborate but also compete with each other, which is ubiquitous in real-world scenarios. Antagonistic interactions of the agents are considered, and modeled as negative weights on the communication graph. We first derive sufficient conditions for consensus in terms of matrix inequalities. Thereafter, a cone complementarity linearization (CCL) based algorithm is proposed for the delay-dependent controller design. The method's framework is formulated in sampled-data settings, to be more realistic and applicable. A numerical example is provided to illustrate the effectiveness of the proposed approach.

In order to save communication consumption in the wireless nodes of networked control systems, this paper investigates the stabilization problem of an event-triggered constrained model predictive control. A state-feedback predictive control law is designed by solving an infinite horizon performance objective and an event-triggered condition involving the norm of a measurement error is derived based on input-to-state stability. Under the proposed mechanism, the measurements are sent by wireless network and the predictive control optimization is implemented only when the triggering conditions are satisfied. This approach not only can alleviate the energy consumption but also achieves the desired control performance and constraints satisfaction. Finally, an example is given to illustrate the effectiveness of the proposed results.

A new attitude and orbit control system (AOCS) software architecture is presented in this paper by using the concept of software bus. According to the analysis of the function flow and data flow of AOCS, its software components are partitioned clearly under the rule of function cohesion and data cohesion, and each component data interaction standard interface is determined as well. Based on such kind of partition, a series of software components with single function are developed to build a component library, which is used for function configuration of AOCS software. Finally, using this library, desired AOCS software can be integrated to follow the mission requirement. During the integration, the software bus is chosen as the communication style of the software architecture to dispatch and manage the components of the software.
