This paper presents a mixed H 2/H∞ performance control algorithm for designing closed-loop pendulous accelerometer controllers. The algorithm aims to enhance the dynamic performance of accelerometers while ensuring robustness and disturbance resistance. By integrating H 2 control and H∞ constraints, the algorithm effectively enhances dynamic performance while countering external disturbances and convex parameter uncertainties. The efficacy and reliability of the algorithm are validated through theoretical analysis and experimentation. A comparative experiments with the standard LQR control algorithm further demonstrate the superiority of the proposed algorithm in terms of robustness and dynamic performance.
