Summary on Grant Application Form |
|
The performance of a feedback system is frequently not robust to saturating actuators. Real actuators are always subject to some nonlinear characteristic (a plant's inputs are always constrained) and the resulting behaviour may be unacceptable. A system whose performance degrades because of nonlinear actuators is generally said to suffer from Windup . The unwanted effects of windup include long term errors in the system outputs, limit cycling and actuator lockup (permanently saturated actuators). The results of a recently completed ROPA project offer a new framework and design methodology for conditioning controllers to overcome the windup problem. This project, will take these results forward and develop new design methods for conditioning which guarantee stability and optimise various measures of performance. Research will look at the design of low-order schemes for their ease of implementation and acceptability by practising engineers.
