By employing electronics and intelligent technology, this paper realizes an effective integration of mechanics and electronics in pipelining packing control. To achieve this aim, stepper motor is controlled by a single-chip microcomputer(SCM) type of STC89C516RD+. Once the photoelectric switch type of LJ-JT02 detects products passing, signals are given out to SCM to direct the stepper motor. Furthermore, the scissors are used to cut off the package tape, which are realized by a relay type of HRS4H-S-DC5V. The experimental results show the effectiveness of above design.
This paper proposed a design method for delay-dependent robust H-infinity filter of linear systems with uncertainty and time-varying interval delay. The proposed method was shown to be much simpler than existing ones while giving significant improvement to the existing results. The key step in the method was to construct a special type of Lyapunov functional for the filter design problem. Unlike the existing techniques, the proposed method employed neither free weighting matrices nor any model transformation, leading to reduced computational demand as well as improved performance. Numerical examples were given to demonstrate the effectiveness of the proposed method.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
