Attitude Control of Missile with Time-delay

Controllability of Switched Linear Systems

第25届中国控制会议

作者： Qiao yupeng,cheng Daizhan Academy of Mathematics and Systems Science,Chinese Academy of Sciences,Beijing 100080

＜正＞In this paper the Fliess expansion is used for attitude control of missile to consider the case when the control is piece-wise. In practice,the control can only be realized with two modifications: （i） instead of rectangle controls "we can only have trapezoid controls";（ii） the controls must have certain time delay. In this paper the tracking problem via delayed trapezoid controls is considered. The theoretical results are applied to the attitude control of missiles.

This paper considers the controllability of switched linear *** largest controllable subspace,C,of a switched linear system is well known [6].This paper shows that when the system is not completely controllable,C divides the state space into 2 or 3 path-wise connected invariant *** we consider whether each path-wise connected component is a controllable *** sufficient conditions are obtained for each sub-manifold to be a controllable sub-manifold.A few examples are given to demonstrate the result.

Peroxynitrite（ONOO-） is a highly reactive nitrogen species that plays pivotal roles in cell signal transduction and physiological or pathological progresses. However, commonly used ONOO-optical imaging probes are still hampered by high background/autofluorescence（fluorescence probe）, short emission wavelength, or poor selectivity in the case of chemiluminescence. Herein,we report a facile method to prepare an activatable chemiluminescence probe（PPA-PEG） with good biocompatibility and functionality for in vivo autofluorescence-free imaging of ONOO-. The PPA-PEG consists of pyropheophorbide-a（PPA）, a typical deep red photosensitizer that acts as both the recognition and signaling element, and 4-arm poly（ethylene glycol）(4-arm PEG), which improves the biosafety and water solubility of probe. These components can self-assemble into nanoparticles（namely PPA-PEG nanoprobe） in aqueous solution. The PPA-PEG nanoprobe showed an ultra-low chemiluminescence signal before interacting with ONOO-, but exhibited good selectivity, high sensitivity and a fast response toward ONOO-. The PPAPEG was successfully applied to image cellular ONOO-changes, as well as the endogenous ONOO-changes in inflammation models and subcutaneous or orthotopic hepatocellular carcinoma（HCC） tumors models in living mice. In vitro and in vivo studies verified the good detection and imaging capabilities of PPA-PEG for peroxynitrite, demonstrating suitable tissue penetration and a high signal-to-background ratio（SBR）. Thus, our nanoprobe can serve as a valuable activatable chemiluminescence imaging tool for studying important peroxynitrite-related chemical and biological applications.
