Abstract:

Proposed in this paper is a flow-coupled secondary regulation system （FSRS） integrated with flywheel energy storage, which recovers the potential energy dissipated as heat energy in the load downward process, stores it as the kinetic energy of flywheel and reuses it in the system. Thus, the difficulty in connecting hydraulic cylinder （fixed hydraulic motor） in the conventional pressure-coupled secondary regulation system （PSRS） is resolved and the conventional PSRS is extended. Afterwards, a mathematical model of the system is established and simulated. As the simulated results accord is correct. It is also found that input voltage is more than 4 V. well with the experimental ones, a conclusion can be drawn that the proposed model the nonlinearity of the system with a response time of 4 s becomes serious when the
