This paper focuses on an integral sliding mode control(ISMC) algorithm for the fault-tolerant control of linear continuous multi-input systems with non-smooth nonsymmetric actuator dead-zone failure and unmatched *** dead-zone is first modeled as a combination of a line and a disturbance-like term. And the novelty of the paper lies in that the treatment of the deadzone failure based on the simplified dead-zone model. The bounded disturbancelike term which enters the state equation at the same point as the control input can be rejected completely by ISMC technology, and the linear part of the deadzone will be compensated by state feedback controller based on linear matrix inequality(LMI). It is worth pointing out that once the system is in the sliding mode, the proposed integral sliding mode control law ensures that the dead zone is compensated completely and sustains the better nature of performing unmatched perturbations attenuation than utilizing H∞ control analytical technique alone. Finally, the feasibility of our proposed algorithm is illustrated by using a numerical example.

This paper researched into the delignification mechanism and the relations of black liquor lignin content and alkali concentration to pulping time under the cooking process conditions of wheat straw sodium sulfateanthraquinone(AQ) pulping with Microwave radiation. The results showed that delignification process was divided into two stages: quick stage and slow stage. The lignin removal rate in the first stage was much higher than the second stage, that is, lignin has been removed more sufficiently after quick stage. In this stage, reaction order of delignification was 1.5, and 0.5 with respect to OH-, the activation energy was 51.90 kJ • mol-1. The latter delignification belonged to the first-order reaction and 0.3 with respect to OH-, the activation energy was 72.20 kJ • mol-1KJ. Apparently, slow stage needed to consume large amounts of energy to removal lignin.
