| Abstract: | The principle of aero-engine rotating speed control system based on DSP is introduced.According to the measuring principle of aero-engine rotating speed sensor and the demand of the digital electronic control system based on TMS320F2812,a rotating speed sensor modulation circuit is designed,then the simulation of the circuit is performed by an advanced circuit design and simulation software Altium Designer 6,and the function of the modulation circuit is validated.On the other hand,a new method of frequency acquisition is proposed,the EV module of TMS320F2812 is used to implement the frequent signal data acquisition,and the accuracy is very high when the input signal frequency range is wide. |
