This paper describes the design and experimental
implementation of a discrete-time fixed-order H∞ controller
for a DC motor position control. Based on grey box modeling,
a model of the DC motor is identified. An extension of
HIFOO toolbox to discrete-time controller design developed
recently is used to synthesize the controller. The performance
of the designed controller in comparison with various control
strategies is demonstrated. The paper aims at demonstrating
simple modeling and control synthesis techniques with the help
of available software tools to design low-complexity controllers in terms of design and implementation. Consequently, cheap
hardware can be utilized for several applications.
