According to the pressure chamber outside interference, voltage instability and error detection of pressure and other factors lead to the problem of zero drift, the zero drift elimination algorithm based on adaptive tuner rectification and resonant self-tuning was proposed. In this scheme, the 3D spatial analysis was established according to the multiple pressure sensors outside interference vector, built-in resistance and the nonlinear coefficient based on characteristic firstly, caused by outside interference factors of the working voltage of the system change and design of self-tuning rectifier circuit, and then analyzes the security conditions necessary for pressure sensor in the resonant state, design the resonance self-adjustment circuit and power amplifier, finally proposed the zero drift of harmonious self-tuning rectifier vibration self-phase modulation with the elimination algorithm. The experiments show that the proposed scheme is superior to the compact multi pressure sensors and capacitive pressure sensor such as the detection precision, anti-disturbance and system stability etc.
