The surgical removal of lesions is among the most common and effective treatments for atherosclerosis. It is often the only curative treatment option, and the ability to visualize the full extent of atherosclerotic plaque during the operation has major implications for the therapeutic outcome. Fluorescence imaging is a promising approach for the inspection of atherosclerotic plaques during surgery...
An adaptive switch gain time-varying sliding mode controller is designed for the low speed servo system in a control moment gyroscope (CMG). By introducing the integral of speed error in the sliding mode surface, the error is suppressed during the whole operation. A time-varying sliding mode controller based on error reference is proposed to solve the problem that normal time-varying sliding mode...
The circulating current among the paralleled solid state transformers (SSTs) originated by the line parameter and mismatched output impedance comes into appearance in the islanded operation of the novel microgrid, the future renewable electric energy delivery and management system. In this regard, the aggregated control strategy of both virtual inductance and external inductance is proposed in this...
