Abstract
In this thesis, adaptive gain of Proportional-Integral (PI) controller and gain
scheduling PI controller to optimize the parameters of the PI for speed control of
a universal motor are presented. The PI gains are allowed to vary on-line and
automatically in order to avoid tedious task in manual control which eliminates the
problems faced by the conventional PI controller. For conventional PI controller,
the PI gains are optimized by trial and error method.
The open loop system performance is studied during starting up, transient and
steady state operations. Experimental results are presented to validate the
simulation results.
The performance of the gain scheduled PI controller is simulated and compared
with conventional fixed PI controller. A high performance is achieved with a
simple control circuit.
In adaptive PI controller, their gains are allowed to vary on-line with motor
speed and load variations. The performance of the system is tested through a wide
range of speeds as well as with load variations through simulation using
MATLAB/SIMULINK and experimental results using DSP 1104.The simulation
and experimental results show that the adaptive PI controller can be efficiently
used for tuning parameters of the PI controller under distinct operation conditions.
