In order to improve the coordinated tracking control performance for the speed and tension system of reversible cold strip rolling mill, a backstepping control strategy is proposed based on command filter in this paper. Controller for each of the speed and tension subsystems is designed based on backstepping respectively, meanwhile the command filters are adopted to generate the virtual control inputs...
A smart home control system could link independent electric appliances together 'intelligently' and provide comprehensive, fast and smooth exchange of information. This system gives people real-time information control, which improves their life quality. In this study, an embedded smart home system based on socket network connections was designed using ARM9 development board and embedded Linux operating...
When multiple T-type three-level photovoltaic grid-connected inverters with common AC bus and DC bus are operating, the circulating current takes place among the parallel-connected inverters due to the line impedance difference, non-synchronized operation of switching devices and inconsistency of comprehensive parameters. The following methods are proposed in this paper, control strategy based on...
The active fault-tolerant control (FTC) with multiple performance constraints is investigated for a class of discrete-time systems subject to sensor faults. A satisfactory FTC strategy by way of the online moving horizon control mode is proposed to guarantee the closed-loop stability of the faulty system. The corresponding soft-constraint based FTC controller design method is developed from the predictive...
In this paper a cooperative control method of centrifugal compressor's flow and pressure is proposed. Base on the analysis of the inherent characteristic of centrifugal compressor and the response time of actuators, a cooperative control strategy is obtained. This control strategy can adjust the flow's and pressure's trajectory in time which let the operating point of centrifugal compressor change...
