The P330 also reports sensor excitation voltage
and frequency and includes built-in self-test.
In the experimental range, sensitivity of displacement has nonlinear relationship with the excitation voltage
. With the excitation voltage
increasing and decreasing, the phenomenon of hysteresis is becoming more and more serious.
A linear response of the device M" (V) versus the square diameter of the specimen on the cylindrical shape as measured when the excitation voltage
[U.sub.G] = 125 V and frequency f = 530 Hz are fixed (Figure 6).
Therefore, the transfer function of the excitation voltage
and current is as follows:
3, the outputs of functional blocks PID-regulators MTDG dependent on given excitation voltage
and speed, which in turn depends on the load on the power that corresponds to a moving boat or dynamically positioned, and the input (inputs) models PID-regulators the rotation frequency of T.
Figure 3 shows the rotor speed, rotor angle and terminal stator voltage responses to the 5 % step change of the rotor excitation voltage
from the nominal operating point (i.e.
The control system's objective is to maintain the generator terminal voltage constant by controlling the excitation voltage
. This issue is presented in many papers, most of them analyzing a normal operating regime, perturbed by the variation of the mechanic torque or by load/unload conditions (usual perturbations which can produce reasonable variations of the controlled terminal voltage) .

The IN-UVI supplies a highly regulated bridge excitation voltage

The DC voltage parameter [[delta].sub.0D] is 1% of the AC excitation voltage
. Figure 2(a) shows the amplitude-frequency response of the resonator, where the frequency is given by the detuning parameter [sigma], (13), and the amplitude [U.sub.max] is the dimensionless vibration amplitude of the cantilever tip with respect to the initial gap distance between the cantilever and ground plate.
