| 英文摘要 |
| In order to simplify the calculation of the nonlinear adaptive L2–gain control (L2–NAC) and improve the
convergence speed of the state variables, by adopting additional control variable and K–class functions, the γ–dissipation
inequality will not be considered in virtual function design and the control ability of L2–NAC can be improved with the
increase of error-variable values, the common formulas of the L2–NAC with K–class functions and additional control
variables (K–L2–NAC) is deduced. K–L2–NAC simulation results of the harmonic excitation system for military power
station show that the K–L2–NAC, comparing with the traditional L2–NAC method, can improve the convergence speed of
the control variables and enhance the dynamic stability of the excitation system for military power station. |
