Project

Stationary Frame Control of Three-phase Converters using Complex Resonators

Background:

Converters for grid-connected and drive applications typically use current control to regulate the injected active power or the applied electrical torque, respectively. In recent years stationary frame control has emerged as a tractable method for implementing current control. Most stationary frame controllers are based on the continuous resonant controller. Practical implementation requires that all continuous transfer functions be discretized, leading to a possible degradation in controller performance. An interesting alternative for three-phase applications is the one-pole complex resonator. As a complex transfer function, the complex resonator has single-sided frequency response rendering different behavior to the continuous resonant controller. Moreover, the complex resonator is directly implemented in the discrete domain thereby avoiding a loss of fidelity in a discretization process.

Project description:

In this project the candidate will develop a current controller structure based on the complex resonator. The performance of the complex current controller will be compared to that of a continuous and discretized resonant controller.

Tasks: Depending on the student’s ambitions, the project may consist of the following steps:

-       Literature review of synchronous and stationary frame current controllers.

-       Development of simulation model for benchmarking the continuous and discrete controllers.

-       Develop an opportune complex resonator structure for use as a current controller.

-       Compare the performance of continuous resonator and complex resonator current controllers.  

-       Implement the complex resonator in a lab setup (to be decided between the student and supervisor).
