| Abstract: | This paper builds up a model of the closed-loop non-linear Hydraulic PCU of aircraft major operational system,based on the state-of art hydraulic drive and control theory,and the modeling method and simulation of utilizing system equation is discussed directly based on SIMULINK.In order to optimize the dynamical characteristics of the system,a proper systematic error functional is employed and some of the structural parameters are optimized immediately using combination of the SIMULINK and optimization toolbox of MATLAB. |
