Target acquisition algorithm based on Sliding Mode Control (SMC) is proposed for TV tracking system. Target acquisition capability and performance are both improved
attributing to overcoming the deficiencies of traditional linear control. In this paper
sliding surface with variable coefficient and continuous control law without switching is introduced in the SMC controller design. The improved SMC shows better performance compared to basic SMC
and full-field acquisition with rapid response and non-overshoot is achieved. The simulation of acquisition shows that
the system can acquire a target passing through the view field of 1.53 in the width with an uniform speed of 15 /s
while the whole process is in a short settling time and chattering-free
and the reaching segment has no overshoot. 2010 IEEE.

In the device
a He-Ne laser of flash frequency 1-20 Hz was adopted as exciting light source
and three key technical problems have been solved successfully in order to enhance the detecting sensitivity and measuring stability of the device for time-resolved fluorimmunoassays(TRFIA) [1]. The first one is to design optimum exciting optical system
so that the exciting light beam excite the sample most effectively. The second one is to have a project spectrum filter which can reduce the affection of the background light to the photomultiplier tube and also ensure influence of the stray light and mixed diffusion light to the sample fluorescence to the least
the sample fluorescence through the integrating sphere and come to the grating monochromator
The right wavelength will be chosed through changing the angle of incidence of the grating monochromator. The third one is to simulate the principle of sample averaging of BOXCAR averager. In the device
SCM was used as primary controller and CPLD was used as timing controller. Through the preparation process
signal-to-noise ratio(SNR) will be improved
also adjust delay time
ampling frequency and sampling number arbitrarily. By testing
the sensitivity is 10-12mol/L(substance marked by Eu3+)
examination repeat is &le2.5%
examination linearity is from 10 -8mol/L to 10-12mol/L
correlation coefficient is 99.98%(p&le0.01). The instrument is advanced for ultrasensitive detection of antigen and antibody
and solve the tumor
genetic variation
the virus protein detection. 2009 SPIE.
