Discrete synchronous reference frame proportional integral Current Controller (CC) delivers superior control performance for high-speed drives due to its ability to accurately compensate for cross-coupling terms. Complete compensation can only be achieved if the machine parameters and operating conditions do not change considerably during operation, however, this is not the case for many aircraft applications. For example, aircraft electrical starter-generator system operating frequencies can change significantly due to the engine’s large speed range. This paper therefore thoroughly investigates the dynamic performance of the discrete CC considering a wide variation of the machine parameters and operating frequencies which has not been addressed in the literature. A multivariable discrete-time domain model of the current control system is proposed for the assessment of the dynamic performances under different operating conditions. The addition of an active damping element has also been considered to improve the disturbance rejection capability of the complex vector decoupling approach. The key paper findings have been successfully confirmed by comprehensive time-domain simulations.
