Figure 3 car mirror wiper system with robust pole placement method
The state equations for the closed-loop system of Figure 3 can be written by inspection as
The poles for this system is chosen as
Solving using Matlab the robust pole placement algorithm gain will be
Result and Discussion
In this section, the Simulink model design and simulation of the vehicle windshield wiper system using H infinity loop shaping and robust pole placement controllers by comparing the two proposed controllers for tracking the step and sine wave speed references.
Comparison of the proposed controllers for tracking the step speed reference
The Simulink model of the vehicle windshield wiper system using H infinity loop shaping and robust pole placement controllers for tracking the step speed reference is shown in Figure 4 below.
