Grid-Side Converters Control and Design
Abstract
This chapter provides the analysis, design, parameter setting, and evaluation of synchronous frame decoupling current controller. Discussion includes all the practical aspects of discrete-time implementation, and it includes discrete-time nature of the PWM voltage actuator and the feedback acquisition systems which are described in the preceding chapters. The analysis and design of discrete-time current controllers rely on z-transform, and it takes into account all the transport delays caused by the feedback acquisition, computation, and PWM processes. Although the scope does not include the code writing, some basic notions related to the interrupt execution and scheduling are also taken into account.
