The problem of recovering the control systems with a complex structure that lost the stability margin due to a malfunction is considered. It was suggested to estimate the potential effectiveness of reconfiguration options by sensitivity functions of the signal graph determinants. Complex-frequency method...
You need to determine the stability of electric power circuits as parameters change due to aging or temperature changes. Frequency response analysis is an important tool in circuit design and verification. Various measurements such as power supply rejection ratio, compo...
This paper deals with the exponential stability analysis of decentralized, sampled-data, Linear Time Invariant (LTI) control systems with asynchronous sensors and actuators. We consider the case where each controller in the decentralized setting has its own sampling and actuation frequency, which ...
The analysis results in sets of frequency conditions, which guarantee transient stability for the entire initial load angle range, between the unstable equilibria neighbouring the system''s operating point, in the case where all other state variables are initially in equilibrium. This property ...
2) frequency domain criteria 频域准则 1. The requirement and reason of frequency domain criteria for handling qualities of pitch axis are briefly presented in the flying qualities MIL STD 1797A in this paper. 简要介绍了军用飞机飞行品质 MIL- STD- 1 797A中有关俯仰轴频域准则的要求和原由。3)...
They use a strip method converting the hydrodynamic coefficients obtained in the frequency domain to be converted for the use in the time simulation. In the Hamburg model basin, Blume and Brink (2001) set up model testing for validating the prediction of extreme roll up to capsizing. Clauss, ...
time-domain analysis; frequency-domain analysis Summary A number of methods have been proposed that utilize the time-domain transformations of frequency-dependent dynamic impedance functions to perform a time-history analysis. Though these methods have been available in literature for a number of years...
Calculating the AC closed-loop gain In Part 1, the closed-loop transfer function of the non- inverting op amp configuration in the frequency domain was calculated. Specifically, the transfer function was derived with the assumption that the op amp had a first- order open-loop response. For ...
Frequency domain criteria for robust D -stability of mimo systems based on LMI method多项式矩阵强D稳定性线性矩阵不等式参数不确定度The problem of checking robust -stability of multi-in and multi-out (MIMO) systems was studied. Three system models were introduced, multilinear polynomial matrix, ...
A generalized eigenvalue is used to estimate whirl-flutter stability in the frequency domain, and the Runge-Kutta method is used in the time domain. Control system flexibility is further included in the present analysis to give the capability for a more accurate stability prediction. Results from...
