A new control method is presented to drive the drive axis of a Micro-Electro-Mechanical Systems (MEMS) gyroscope to resonance and to regulate the output amplitude of the axis to a fixed level. It is based on a unique active disturbance rejection control (ADRC) strategy, which actively estimates and compensates for internal dynamic changes of the drive axis and external disturbances in real time. The...
A new control method is presented to drive the drive axis of a MEMS gyroscope to resonance and regulate the output amplitude of the axis to a fixed level. It is based on a unique active disturbance rejection control (ADRC) strategy, which actively estimates and compensates for internal dynamic changes of the plant and external disturbances in real time. The stability analysis shows that both the estimation...
This paper presents a new control strategy known as active disturbance rejection control (ADRC) for controlling the sense axis of a vibrational MEMS gyroscope and detecting time-varying rotation rates. In the ADRC framework, the generalized disturbance, which is referred to as the combination of the internal dynamics and external disturbances, is estimated and compensated for in real time. It is assumed...
