Figure 7 Simulation result for a sine wave reference input
The simulation result shows that the vehicle windshield wiper system
with H infinity loop shaping controller track the reference speed better
than the vehicle windshield wiper system with robust pole placement
controller.
Conclusion
The vehicle windshield wiper system is designed and simulated based on
the given control signals using Matlab/Simulink and a promising result
have been analyzed. The performance of the vehicle windshield wiper
system is tested for wiping speed regulation using track a signal
method. Comparison of the vehicle windshield wiper system with H
infinity loop shaping and robust pole placement controllers is done for
a step and sine wave reference speed signals and the vehicle windshield
wiper system with H infinity loop shaping controller shows a good result
in improving the wiping mechanism in almost the all performance measures
taken. Finally the comparative results prove the effectiveness of the
proposed H Loop Shaping controller to improve the wiping mechanism for
the given two reference signals.
