Research on Parameter Design and Control Method for Current Source Inverter–Fed IM Drive Systems

چکیده
In the current source inverter (CSI)-fed inductor motor (IM) drive system, DC-bus inductance and AC-filter capacitance have a direct impact on dynamic response speed, power quality density. addition, due to addition of filter capacitors, mathematical model formed by IM capacitor is third-order which increases difficulty parameter tuning for control loop. To solve above problems in CSI, design method based speed ripple DC-link an utilization filtering characteristics are presented. Then, analytical expressions between open-loop cut-off frequency, phase margin PI controller parameters loop derived. Finally, experimental platform established validate proposed method.

Speed Control of A Three Phase Current Forced Synchronous Machine Drive Based on A Simple Method
In this paper, a new method is proposed for the speed control of a three-phase current forced synchronous machine drive. This metohd is based on the use of an approximate constant commutation safety margin angle in the output thyristor bridge of the drive system as well as on the compenastion of stator magnetization reaction. The commutation process in the output converter of the machine driv...

A Bayesian Method for Robust Tolerance Control and Parameter Design
This paper proposes a Bayesian method to set tolerance or specification limits on one or more responses and obtain optimal values for a set of controllable factors. The existence of such controllable factors (or parameters) that can be manipulated by the process engineer and that affect the responses is assumed. The dependence between the controllable factors and the responses is assumed to be ...
