This study explores polynomial Markov positive fuzzy systems, formulating controllers for these systems by examining the prerequisites for positivity and stochastic stability. Initially, polynomials are incorporated into the Markov positive fuzzy system to represent nonlinear elements better and enhance its capacity to model nonlinear systems. Concurrently, the study discusses the non-convex scenarios encountered in the stability analysis of the closed-loop system once the positive fuzzy system controller is integrated and confirms the stability of the Markov polynomial positive fuzzy system. Ultimately, the effectiveness of the proposed approaches is demonstrated through a numerical simulation example. © 2024 IEEE.

The aerostat power system was designed, it's simulation experiment was conducted, and it's data were analyzed according to the operating characteristics of the aerostat in this paper. The influence of the environmental conditions and different loads on the power supply system was also analyzed because the requirements in all aspects in the aerostats power supply system are very rigorous in the fields of aerospace. A detail researches and analysis on key technologies of the floating power supply system were carried out considering the relationship between illumination conditions and peak power. Then, a design of aerostats' power supply system was brought up based on the energy balance principle. At last, the feasibility of the design systems was verified and some key issues were analyzed in detail through the analysis to low-altitude simulation test data.

International Journal of Automation and computing 2011年第4期8卷 452-458页

This paper presents a symmetric cooperation strategy for cooperative relay networks with multiple users. The multi-user symmetric cooperation model and the relay selection algorithm are proposed. Then, the time slot allocation problem is cast into a bargaining problem, and the optimal time slot allocation solution is obtained by Nash bargaining solution （NBS）. Moreover, we also consider the implementations of the cooperation strategy, i.e., the grouping and admission control algorithm. Simulation results show that users can obtain larger rates under the symmetric cooperation strategy than the non-cooperative case.

This paper deals with the formation control problem for a group of quadrotor unmanned aerial vehicles (UAVs) through a modified dynamic event-triggered control protocol. The stability proof for the state space origin of the overall closed-loop system is derived from the singular perturbation method and Lyapunov stability theory. An event-triggered formation control protocol in terms of a dynamically varying threshold parameter is delicately carried out while acquiring satisfactory resource efficiency, and Zeno behavior of triggering time sequences is excluded. Finally, simulations on four quadrotor UAVs are given to verify the effectiveness of the theoretical results. © 2018 Technical Committee on control Theory, Chinese Association of Automation.

An equalization algorithm based on constellation matched phase error for M-ary phase shift keying signals

引用

Journal of Computational Information Systems 2014年第3期10卷 895-902页

作者： Wang, Xinlin Liu, Bin Li, Haibin Liu, Shuang College of Information Science and Engineering Yanshan University Qinhuangdao 066004 China Key Lab. of Industrial Computer Control Engineering of Hebei Province Yanshan University Qinhuangdao 066004 China

The inter-symbol interference (ISI) and phase error caused by non-ideal character of channel can result in severe degradation of bit error rate performance in communication system. The existing equalization algorithm can effectively eliminate the ISI of M-ary phase shift keying signals (MPSK), but do not inhibit the phase error. A new equalization algorithm that accomplishes blind equalization and phase information recovery simultaneously is proposed for MPSK signals. In the algorithm, the cost function is weighted sum of two separate well-defined terms: one is identical to the constant modulus algorithm case to enhance the robust of the algorithm, and another is a constellation matched phase error (CMPE) term that is constructed in this paper. The CMPE term is used to cancel the phase error of the equalizer output. Simulation results demonstrate that the proposed algorithm is effective in removing ISI and correcting phase error at the same time. © 2014 Binary Information Press.

Based on multi-machine excitation control models, using fuzzy adaptive theory and considering the muti-machine nonlinear system whose states are not available, observer-based adaptive fuzzy output feed back control schemes are proposed. In this paper, the ant colony algorithm is used to optimize the fuzzy control rules. The simulation result shows that the controller can effectively improve power system stability under big disturbance. © 2010 IEEE.

The triple inverted pendulum is a nonlinear, dynamic and unsteady system. The traditional control methods of triple inverted pendulum have limited control accuracy and slow responding. This kind of pendulum system is difficult to control due to the inherent instability and nonlinear behavior. In this paper, GA-RBF-ARX model is applied to model triple inverted pendulum based on its input/output data. According to the nonlinear identification model, a novel method via T-S cloud inference network controller optimized by genetic algorithm(GA) is proposed. T-S cloud inference network is constituted by T-S fuzzy neural network and the cloud model. Therefore, the rapid of fuzzy logic and the uncertain of cloud model for processing data are both taken into account. What's more, GA possesses global optimization characteristics and good parallel design structure. Compared with the simulation recognition results of T-S fuzzy neural network controller, T-S cloud reference network controller has strong robust and fast calculate speed. So, T-S cloud inference network by GA is an effective method in control.

A distinctive new LMS algorithm is proposed in his paper. Both fast convergence rate and small steady state rror can be obtained through non-linear weighting N errors of the current moment and past moments in this algorithm. The algorithm analyzed that the ideal step size is achieved by increasing the error information, building new nonlinear relations between step size factor and error function and eliminating the effect of correlated noise sequences. Then the new algorithm is applied to the fixed satellite communications system in which the channel is affected by multipath effect and weather conditions attenuation. Simulation results show that the new algorithm converges faster than usual algorithms under approximate steady state performance. The signal BER performance is greatly improved with the new adaptive algorithm equalizer in the fixed satellite communications system.

To tackle the multi-objective problem in the process of tandem cold rolling, a mathematical model of multi-object optimization is presented. Taking equal relatively power and prevent slippage as objective functions. Aiming to the problem of Standard Genetic Algorithm (SGA), such as premature convergence, oscillation and over-randomization in iterative process, an Improved Adaptive Genetic Algorithm (IAGA) is applied to optimize the system. The algorithm decides the crossover rate and mutation rate of chromosome based on individual adaptive value in calculation process, make the start phase mutate obviously and later phase stable slowly and ensure the population development, seeking balance and entire convergence. Simulated results show that, in comparison with the actual rolling schedule, the optimization rolling schedule makes the reasonable distribution of tandem cold rolling power, gives the full play to equipment capacity, reduces the rate of slippage, improves the product quality, and the proposed method is demonstrated to be competent. ©2010 IEEE.
