Convex parameterization of uncertain pendulous accelerometer with mixed [formula omitted] robust optimal control.

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. • Analysis of accelerometer systematic errors under varied conditions, with a torque integral-based controller design strategy. • Clear quantification of accelerometer failure constraints under parameter uncertainty. • Proposed Novel mixed H 2 / H ∞ algorithm enhances accelerometer dynamic performance and robustness. • Experimental evidence demonstrates the superiority of mixed H 2 / H ∞ control over standard LQR.
