Abstract
Rotating machinery is a component of several machines such as wind turbines, aeronautical engines, compressors and many other industrial appliances. For high efficiency, the rotor-blade system must comply to rigorous low vibration levels. Passive vibration can be considered, but it is effective only at specific operational settings and features limited dampening when compared to active control. Since rotor-blade systems exhibit periodic dynamics, linear time invariant strategies can neither ensure closed-loop stability nor acceptable performance. Periodic controllers with guaranteed closed-loop stability and performance still feature numeric implementation problems when the period is large or when the system's equation coefficients display large variation along the period. Further difficulties arise when it's impractical to measure, in real-time, physical quantities that describe the motion of rapidly moving machine parts. This work presents the design of a multiple frozen models H2 controller. Numerical results show the benefits of the proposed approach.
