Paper Abstract

Excitation current and torque current are decoupled through vector control in frequency converter, so the linear control method can be used in speed loop. Pseudo derivative feedback with sub-variable control (PDFSV) has excellent performance and easy to realize. Its control parameters are obtained through present equation which is related to inertia parameter. To the frequency converter system with parameter changes at extensive range, the PDFSV control with variable control coefficient is presented: to construct full-order state observer, to observe the speed error signal which contains error information on the moment of inertia and calculate control coefficient by presented equations, and feed forward the observed load. The simulation results show that the speed control response performance well when the moment of inertia and disturb load varied at extensive range.
