V/I电路在航空发动机电子控制器上的应用

A Novel Digitally Controlled DC Current Source

在航空发动机控制系统中,存在着大量直流驱动负载,如力矩马达、电液伺服阀等。高精度,高稳定性的直流驱动电路对发动机控制系统的性能有着至关重要的影响。针对以往采用分立元器件设计的电路,精度较低,电路设计复杂,采用集成元器件设计直流驱动电路,提高了系统精度,简化了电路设计,同时降低了设备的重量和体积。

In the aircraft engine control system,there are a large number of DC-driver loads,such as toque motors and sevo-valves and so on.Featured by high accuracy and high stability,the DC driver-circuit has a crucial influence on the performance of the aircraft engine control system.Different form the previous circuit designed with discrete components,this paper designs DC-drive circuit with the application of integrated components,which improves the system accuracy,simplifies the circuit design and reduces the weight and size of the equipment as well.
