Abstract Globally abundant wave energy for power generation attracts ever increasing attention. Because of non-linear dynamics and potential uncertainties in ocean conversion systems, productivity needs to be increased by applying robust control algorithms. This paper focuses on strategies a small system based direct driven permanent magnet synchronous generator (PMSG). It evaluates the perform...

In this paper a sliding mode controller (SMC) is designed for a permanent magnet direct current (PMDC) motor to enhance the motor performance in the presence of unwanted uncertainties. Both the electrical and mechanical signals are used as the inputs to the SMC. The complete motor control system is simulated on a personal computer with different design parameters and desirable system performanc...

Abstract At present, automatic control technology is widely used in the field of drying. Although existing processing can basically ensure quality drying, there are some problems, such as low production efficiency, thermal uneven hot air cloth, inaccurate temperature and so on. The application electromagnetic improve efficiency drying processing. It has remarkable energy-saving effect. In proce...
