The proposed piecewise controller design method can get a better disturbance-attenuation performance when the frequency ranges of disturbances are known beforehand.
Numerical results show that the proposed RVS-TMD system can avoid detuning effect automatically and assure the optimal control performance as desired when the frequency of primary structure is changed.
In stationary signal case, the variance and mean bias values versus SNR performance when estimating the frequencies of two cisoids in additive white and colored noise has been presented, and compared against the CRB for white noise as well as against the performances of the Periodogram, multitaper, Capon, APES, and IAA methods.
It has been shown, that ADHD patients are able to show unimpaired performance when a task is more intriguing or when the frequency of target stimuli is high [Corkum and Siegel, 1993; Friedman-Hill, 2010].
For example, when the frequency of the primary noise is set as Hz, all the approaches have the same convergence performance and speed as illustrated in Figure 10.
While WCDMA-based cellular networks use OVSFrequencyor channel allocation, variable spreadomainactor orthogonal frequency code divispreadingiplexingivesF-OFCDM) has betterroposed as the transmission scheme for 4G next-generation cellular networks [7–9].
NSV is said to occur when the frequency of the instability coincides with a blade mode frequency.
Now, with the increased traffic load, it becomes even more difficult to achieve good performance when the mode switch frequency, and thus the number of routing control packets, becomes too high.
When asked about the frequency of conducting performance appraisal, 77.3% reported conducting annual performance appraisal for all of their employees in the hospital (see Table 3).
