Research on Gain Scheduling: Quiet Past. Noisy Present! Symphonic Future?

After decades of silence on the subject, the academic research community in the 1990's has taken up the topic of gain scheduling for nonlinear control design with increasing interest. This has led to the formalization and clarification of some old ideas in gain scheduling, and to some new ideas that are making their way into practice. After a review of some early examples of gain-scheduled control, a number of current and future research directions will be discussed.
