Furthermore, to eliminate the chattering resulting from the discontinuous switch controller and to guarantee system transient performance, a new adaptive fuzzy sliding mode controller was designed.
      
In this paper, a new feature extraction method for radar pulse sequences is presented based on structure function and empirical mode decomposition.
      
In this method, 2-D feature information was constituted by using radio frequency and time-of-arrival, which analyzed the feature of radar pulse sequences for the very first time by employing structure function and empirical mode decomposition.
      
Under the high bending vibration mode, resonance frequency and other parameters of longitudinal and radial wood were tested.
      
The typical frequency response function chart of the whole machine and its sanding parts, as well as its second-order mode charts of contacting roller, were obtained.
      
Assessment of the effect of a fully closed hillside afforestation mode on the natural Pinus tabulaeformis forest
      
Since 1950, a mode of fully closed hillside afforestation (FHA) has been applied in the forest.
      
tabulaeformis forest ecosystems were generated by sensitivity analysis and an assessment index system for the FHA mode was established.
      
According to the equal distance method, a clustering technique and five grades of an integrated index for evaluating the FHA mode were compartmentalized.
      
The effect of the FHA mode on natural secondary P.
      
The results are as follows: values of the integrated index in the FHA mode of 16, 25, 30, 45, 60 and 75 year old stands were 7.25, 6.88, 7.82, 5.51, 4.78 and 2.79 respectively.
      
With an increase over age of the FHA stands, the effect of the FHA mode deteriorated.
      
Based on the relation of time-frequency distribution of the acoustic leak signal and the dispersion curves of guided waves, the mode components of acoustic leak signals were obtained.
      
The research can provide a guideline for the mode selection in pipeline leak location, and help improve the accuracy of leak location.
      
A sliding mode perturbation observer (SPO) is designed to estimate unmeasurable states and system perturbations that involve system nonlinearities, disturbances and unmodelled dynamics.
      
From the different results, we find that the motion of an astronaut's arms has greater influence over space walking with the same control mode.
      
A new acoustic emission source location technique based on wavelet transform and mode analysis
      
Output tracking control of mobile manipulators based on dynamical sliding-mode control
      
A dynamical sliding-mode controller is devised to track the output of mobile manipulators.
      
Moreover, a design method of the dynamical sliding-mode controller that is applied to the output tracking of mobile manipulators is proposed.
