Abstract

The paper mainly focuses two major areas of electromechanical actuator
system composed of power screw, spur gear train and Brushless DC Servo
Motor. First it describes control of electromechanical actuator system with
three level of current controller which is composed of power amplifier,
DSP module and interfacing circuitry. The non-linear model of the three
level controllers developed in SIMULINK environment is presented. A
second point which was included in this study is the comparison of two
control strategies i.e. three level controller and PWM current controller.
The main outcomes of the study is that three level controller is simple
in construction and much more stable. This is much suitable for higher
reduction systems, short missions and low power density actuators;
however it has few limitation that make it unsuitable for applications such
as high power density, long missions and direct drive system.
