| 摘要: |
| 某型直升机辅助动力装置（APU）原采用机械液压式控制系统（HMC）。因机械液压控制系统结构复杂不易修改且难以实现先进控制算法等原因而该型APU又面临着性能提升等方面的需求，迫切需要对现有的控制系统进行数控改型。在对原控制系统控制律及其与数控系统差异分析的基础上，对数控系统所涉及的总体结构、控制规律、电动燃油供油系统等关键技术重新进行了设计，并最终实现了该型APU的全权限数字电子控制系统（FADEC）。通过台架试车，验证了该FADEC系统功能、性能及其关键技术。试车结果表明，相比原有的机械液压控制系统，所设计的FADEC不仅扩展了APU原控制系统的控制功能，同时也更加有效地发挥了APU的性能。 |

| Abstract: |
| A helicopter auxiliary power unit (APU) is initially equipped with a hydro-mechanical control system (HMC). Because HMC's complex structure is difficult to be modified to realize sophisticated control algorithms and the APU is faced with the need for performance improvement, it is urgently necessary to carry out digital control modification of HMC. Based on the analysis of control laws of the original HMC and differences between HMC and digital control system, key techniques involved in the digital control system are studied, such as overall structure, control laws and fuel system based on electric fuel pump, and finally a full authority digital electronic control system (FADEC) is developed for APU. Functions, performances and key techniques of the FADEC system are evaluated on test rig, and the test results show functions of original control system are enhanced and performances of APU are improved more effectively under the control of the designed FADEC compared with the original HMC. |
