Figure 4 Simulink model of the solenoid based linearly movable armature system using H infinity mixed-sensitivity and mixed H 2 /H∞ with regional pole placement controllers for tracking the step references displacement signal
The solenoid based linearly movable armature system performance for the proposed controllers using a step reference (step change from 0 to 6 m) of the displacement output simulation is shown in Figure 5 below.
