Abstract:
Provided is an accelerometer, and particularly to a quartz pendulous accelerometer, including a quartz meter, which is configured to sense an acceleration signal, convert the acceleration signal into an inertia torque and convert the inertia torque into a quartz meter output signal; a readout apparatus, which is configured to convert the meter output signal into an input signal recognizable by a pulse generating apparatus; a pulse generating apparatus, which is configured to perform control algorithm conversion, oversampling and digital quantization on the input signal to obtain a quantized current pulse, where the quantized current pulse is converted into an electromagnetic pulse torque for balancing the inertia torque. By means of a circuit design and a system stability design of the present disclosure, digital feedback is realized while quantizing a feedback current is implemented. Negative feedback is realized by adopting an oversampling technique, so that the linearity, the dynamic precision etc. of a closed-loop system are realized. In addition, applying a SDM achieves quantized noise shaping so as to realize purposes of low noise and digital quantity output.

Claim (Index 19):
The closed-loop control method for a quartz pendulous accelerometer according to  claim 13 , further comprising: providing an electromagnetic torque pulse control unit, which comprises a timing control unit and a constant-current source unit; and\n the electromagnetic torque pulse control unit receives the quantized current pulse, and the timing control unit determines a direction and a magnitude of an acceleration signal by switching a conduction direction and a number of conduction times of the constant-current source unit by means of timing control, and performs feedback control on an electromagnetic torquer of a quartz meter for balancing the inertia torque.
