This paper mainly studies one dimensional mean-field backward stochastic differential equations (MFBSDEs) when their coefficient g is uniformly continuous in (y′, y, z), independent of z′ and non-decreasing in y′. The existence of the solution of this kind MFBSDEs has been well studied. The uniqueness of the solution of MFBSDE is proved when g is also independent of y. Moreover, MFBSDE with coefficient...
This paper focuses on integral sliding mode output control for linear delta operator systems with insensitivity to sampling time jitter in the case of small sampling times along with unmatched disturbances. A delta-domain integral sliding mode sector can be reached without chattering by employing a novel reaching law to avoid the inherent numerical ill-condition resulting from using the traditional...
This paper applied the factor analysis method to dynamically evaluate the credit risk of listed companies in China. Sixteen measurable indicators which can reflect the public credits of listed companies are selected and 4 main indicators are extracted by applying the factor analysis method. On the basis of it, 16 sub-indicators are further given to explain the affecting level to the credit of listed...
It is worse that steam generator is controlled by PID which is non-minimum system with oscillation. ADRC achieves excellent control performance using nonlinear control law, but it isn't necessarily optimal when adopting standard ADRC structure and NLSEF. In this paper, we optimize the standard ADRC, the simplified ADRC without TD, the improved ADRC with NLSEF using mtfal and zzxfal based on GA. The...
The evaluation of the city public emergency capability is an important basis of the development of the city emergency capability. This paper made a evaluation to the eight sample cities based on the Fuzzy Set Theory. And the sample cities are choice by the three criteria such as disaster distribution, city type and geography location and so on. And they are Nanning, Harbin, Yinchuan, Shenyang, Jinan,...
The general singular Boolean networks (SBNs) are proposed in this paper according to the algebraic form of dynamic-algebraic Boolean networks. First, the solvability theorems of this kind SBNs are presented. Then, the transition matrix of an SBN is defined, based on which the results on fixed points and cycles of SBNs are obtained. Furthermore, general singular Boolean control networks (SBCNs) are...
Aming at the current problem that Electronic whiteboard positioning has the poor accuracy, we propose an improved UKF positioning algorithm. Through adding time-varying fading factor to the standard UKF algorithm, such method can significantly reduce the influence of outmoded data on the current estimation value. Meanwhile, by adding adaptive adjustment factor to alter filtering gain to control the...
Considering the problem of ship lateral motion control, a novel method based on the closed-loop gain shaping algorithm and T-S fuzzy optimization algorithm is proposed. The T-S fuzzy optimization algorithm is applied in the weighted coefficients of roll and yaw in this paper. According to the closed-loop gain shaping algorithm, robust PID controllers to roll and yaw are designed and then they are...
