Piezoelectric cold air variable thrust closed-loop regulation and control device based on multi-sensor fusion

The invention discloses a piezoelectric cold air variable thrust closed-loop regulation and control device based on multi-sensor fusion. The piezoelectric cold air variable thrust closed-loop regulation and control device comprises a shell, a flow sensor, a flow sensor front-end processing circuit, a displacement sensor, a displacement sensor front-end processing circuit, a flow sensor gas temperature sensor, a thruster inlet temperature sensor, a thruster outlet temperature sensor and a piezoelectric cold air thruster. Piezoelectric precision driving and temperature and flow sensor interactive compensation are adopted, the thrust cross-basin high-precision compensation problem is solved, and the high-precision thrust regulation and control problem is solved through multi-physical-quantity feedback. The multi-sensor fused piezoelectric cold air variable thrust closed-loop regulation and control module is also a high-precision flow control module, and can also be widely applied to high-precision and advanced c
