Periodic control has reached a notable degree of maturity thanks to developments over the last few decades. We have seen not only major theoretical achievements but also new significant applications.
The IFAC workshop on Periodic Control Systems (PSYCO 2001), held at the Villa Erba Congress Centre in Cernobbio-Como (Italy), August 27-28 2001, aimed at presenting the full picture of the area by gathering experts in the field and all interested researchers, coming from universities, research institutions and industries.
The program consisted of technical sessions, organized in two parallel streams and two plenary lectures, given by Jason L. Speyer (University of California at Los Angeles, USA) and Yutaka Yamamoto (Kyoto University, Japan). The technical sessions included 42 papers covering the following subjects:
•Periodic Systems Analysis
•Hybrid and Sampled-Data
•Periodic Systems Control
•Multirate and Batch Processes
•Repetitive and Nonlinear Control
A dozen of the papers were devoted to a number of applications, including aerospace, jet and diesel engines, gas turbines, nuclear reactors, power systems, satellites, environmental sciences and finance.
For systems designers, researchers and practitioners with an interest in control.
