hydraulic and pneumatic control components of control systems for surface mounted bop stacks 地面防喷器及控制装置专用液压气动元件
fourthly, many times digital simulations and hardware-in-the-loop simulations have made . those simulations verify and improve on the control system . in the meantime, components of control system are tested in hardware-in-the-loop simulations 第四,进行数字仿真和半实物仿真,检验和改善控制系统,半实物仿真同时也检验了系统所用的元器件。
