摘要：
The design of robust controllers for processes with operating-point-dependent behaviour is a minimax optimisation problem which can, in general, e.g. for given controller structures or for practical relevant performance functionals, only be solved by numerical minimisation. The convergence of the minimisation algorithm is only ensured if the initial point needed to start the optimisation is in the neighbourhood of the local minimum. This makes the design difficult for the engineer because there is no systematic way to find an initial point. The paper presents a contribution to overcome this difficulty by using continuation methods. (C) 2002 Elsevier Science Ltd. All rights reserved.
