Although the energy-based robust controller always guarantees closed-loop stability, it is not easy to find suitable gains of the terms for a satisfactory control performance.
The underlying idea of the DFC approach is that, no matter how complex a system is, as long as its mechanical structure can be judiciously designed such that it can result in a simple dynamic model, a simple control algorithm may be good enough for a satisfactory control performance.
In this context, and searching for a satisfactory control structure, static analysis tools, as RGA and SVD, had been used in the characterization of a set of alternatives structures based on the primary composition control variables L, V, D and B, as well as some relations between them.
If acceptable values for these disturbance rejection measures are not achieved, no controller can achieve satisfactory control.
To ensure satisfactory control performance for the cable-driven manipulators under complex lumped uncertainties, a new continuous fractional-order nonsingular terminal sliding mode (CFONTSM) control scheme based on time delay estimation (TDE) is proposed and studied in this paper.
It is admittedly challenging to identify satisfactory control groups for area based interventions.
While mRNA expression of GAPDH may not be the same in different tissues [ 21], we believe that it was a satisfactory control gene for the present study because both tumor and matched normal esophageal tissues were used and the values for tumor and normal were both normalized to GAPDH as an initial step in the data analysis.
For satisfactory Salmonella control, good biosecurity along the pork production chain is crucial, although additional control measures on-farm need to be considered.
For the MLH1 marker, 26 out of 28 couples for which DNA could be amplified showed satisfactory control of bisulfite conversion.
At present, two levels of A1C are usually recognized as threshold values for satisfactory diabetic control: 7% for the American Diabetes Association (17) and 6.5% for the American College of Endocrinologists (18) and the International Diabetes Federation (19).
