中文摘要：

提出了飞轮储能型二次调节流量耦联系统，该系统可把原来系统负载下降时转化为热能散失掉的势能存储为飞轮的机械动能，并回收利用，不仅克服了传统二次调节系统不宜接入液压缸（定量液压马达）的缺点，还是对传统二次调节系统的拓展．在建立系统数学模型的基础上，通过仿真和试验发现仿真结果与试验结果比较一致，从而验证了数学模型的正确性．该系统调整时间约为4S，并且当输入幅值绝对值大于4V时，非线性程度加剧。

英文摘要：

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
