In this article, we investigate the neural adaptive quantized control problem for microelectromechanical system (MEMS) gyroscope with full-state constraints and lumped disturbances. With two different kinds of one-to-one nonlinear mappings, traditional model matched disturbances is transformed into an unconstrained one both unmatched disturbances, thus predefined time-varying state imposed on MEMS can be achieved. To compensate a estimator-based minimal learning parameter network proposed to...
