The problem of controlling half bridge single phase unity power factor rectifier circuit is considered. The control objectives are to achieve i) output regulation and ii) near unity power factor in the presence of an uncertain load. The considered problem is dealt with using a double-loop controller developed on the basis of the system nonlinear model. The inner-loop is designed using Lyapunov technique...
We are considering the problem of controlling synchronous motors driven through AC/DC rectifiers and DC/AC inverters. The control objectives are threefold: (i) forcing the motor speed to track a reference signal, (ii) regulating the DC link voltage, (iii) enforcing power factor correction (PFC) with respect to the power supply net. First, a nonlinear model of the whole controlled system is developed...
We are considering the problem of controlling AC/DC full bridge converters. The control objectives are twofold: (i) guaranteeing a regulated voltage for the supplied load, (ii) enforcing power factor correction (PFC) with respect to the main supply network. The considered problem is dealt with using a nonlinear controller that involves two loops in cascade. The inner-loop is designed, using sliding...
