摘　　要：对于某水下热动力推进系统实施闭环控制是提高武器效能的需要。通过分析系统的物理特性,给出了适用于控制律综合的系统模型,进行了非线性变结构控制系统的设计。该控制系统跟踪指令准确、快速,抗干扰能力强,且燃烧室压强不超调、安全性好。基于该控制算法而研制的功率控制单元已通过了试验验证。Closed loop control must be used for underwater heat engine propeller system in order to improve the efficiency of weapons. Based on the analyzing system character of physics, the paper broughtforward the mathematic model which was fit for synthesizing control law. The nonlinear variable structure control system was devised. The control system can keep up with the order signal quickly and accurately, make the pressure of combustion chamber not overshoot, and ensure the security of system. Power control unit was developed and proved by tests.
