This paper theoretically analyzed the effects of asymmetric structure and loading characteristic on control performance while using multifunctional integrated valve (MFIV) to control asymmetrical cylinder. An analytical model was developed for studying the systemic characteristic and the pressure-break phenomena at the point the cylinder changing moving directions. This model was implemented in dSPACE (Digital Signal Processing And Control Engineering) environment. Based on the validation results obtained from experimental evaluation using a laboratory setup, the developed analytical model was proved to be able predicating the dynamic behaviors of an asymmetric hydraulic system to support the development of a valve controller to control a MFIV in achieving desired system performance.
