The iterative ADP algorithm permits an arbitrary admissible control law to initialize the iterative algorithm. It is the first time that the properties of the policy iterative ADP are established for the discrete-time situation. It proves that the iterative performance index function is non-increasingly convergent to the optimal solution of the Hamilton-Jacobi-Bellman (HJB) equation. It also proves that any of the iterative control policy can stabilize the nonlinear systems. Neural networks are used to approximate the performance index function and compute the optimal control policy, respectively, for facilitating the implementation of the iterative ADP algorithm. Finally, a simulation example is given to illustrate the performance of the present method.","PeriodicalId":90521,"journal":{"name":"IEEE International Conference on Systems Biology : [proceedings].

In this paper, a novel multiple target localization approach is proposed by exploiting virtual fingerprinting, which is calculated from spacial relationship between reference nodes and virtual location nodes. The merits of our proposed method is twofold. First, our proposed method does not require the process of RSS fingerprinting constructing, which is a huge burden of localization methods based on RSS. Secondly, our proposed method is more robust than some existing methods, such as TOA-based method and RSS-based method, in big measurement error case. The efficacy of our proposed method are proven by means of some experimental results.","PeriodicalId":90521,"journal":{"name":"IEEE International Conference on Systems Biology : [proceedings].

The T-S fuzzy model consists of N interconnected discrete-time Takagi-Sugeno (T-S) fuzzy subsystems, the decentralized control scheme is adopted and the communication links between the subsystem and controller are assumed to be imperfect, that is, data packet dropouts occur intermittently, which is often the case in a network environment. The data loss is modelled as a random process which obeys a Bernoulli distribution. A piecewise state feedback decentralized controller is designed to stabilize the networked interconnected fuzzy system in the sense of mean square and also achieve a prescribed H ∞ model reference tracking performance based on a piecewise Lyapunov function. Moreover, the required H ∞ controllers can be designed by solving a set of linear matrix inequalities (LMIs). A simulation example is given to show the effectiveness of this approach.","PeriodicalId":90521,"journal":{"name":"IEEE International Conference on Systems Biology : [proceedings].

The main reason forming the charged colloidal crystal is that the charged colloidal particles achieve a balance and long orderly arrangement because of the static repelling force between particles and granular Brownian movement. However, the slight fluctuations temperature will cause the strength of Brownian motion changes and then influence the crystallization of colloidal crystal state and crystallization process. This paper solves a key work on the research of colloidal crystal phase dynamics: colloidal crystal solution of high precision low volatility temperature control system. A proportional-integral-derivative (PID) control method based on pulse-width modulation (PWM) is proposed. Then, system identification on the heating system of the sample solution is used to get transfer function, and Hooke-Jeeves pattern search method is used to get optimal parameters of the PID controller.","PeriodicalId":90521,"journal":{"name":"IEEE International Conference on Systems Biology : [proceedings].
