This paper presents the application of the proportional-integral-derivative （PID） controller to the flight control system （FCS） for two-dimensional （2D） differential geometric （DG） guidance and control problem. In particular, the performance of the designed FCS is investigated. To this end, the commanded angle-of-attack is firstly developed in the time domain using the classical DG formulations. Then, the classical PID controller is introduced to develop a FCS so as to form the 2D DG guidance and control system, and the PID controller parameters are determined by the Ziegler-Nichols method as well as the Routh-Hurwitz stability algorithm to guarantee the convergence of the system error. The results demonstrate that the designed controller yields a fast responding system, and the resulting DG guidance and control system is viable and effective in a realistic missile defense engagement.

An improved synchronous fluorimetric method for the determination of dissolved organic matter in cave drip water, by adding ascorbic acid, is described. The method is based on the redox reaction between ascorbic acid and the electron-withdrawing constituents in dissolved organic matter. The results show that adding ascorbic acid can quench the minor peaks, at 200-300 nm, but does not affect the intensity of the main peaks at 300-500nm. In addition, adding ascorbic acid can maintain relatively high and constant fuorescence intensity over a wide pH range （9-4）.

作者： liquan Wu Sai Chen chaoyong li College of Electrical Engineering Zhejiang University

In this paper, we investigate the performance evaluation of multiple missiles. To this end, information entropy and IAHP are introduced to develop a combined algorithm to compare the performance of different parameter configurations, and we analyze some typical factors affecting a cooperative guidance law with impact angle constraint. The proposed algorithm is fully comprehensive and capable of combining subjective experience with objective data, and the performance of the introduced guidance law against maneuvering target is rigorously analyzed. Simulation results verifies the feasibility of the proposed method.
