In this paper a cooperative Fuzzy model predictive controller (CFMPC) for a multivariate process is presented. Instead of designing one multivariate Fuzzy model predictive controller (FMPC) several more simple FMPCs for the input-coupled subsystems are designed, and optimal behavior is guaranteed by a cooperative iteration-loop. This ensures added flexibility in changing and extending the control...
There is a class of control algorithms, which are based on models of the controlled processes. The common feature of these algorithms is the fact that at the design stage the algorithm can be modified to take into account multiple sensors available in the controlled plant. Each additional independent measurement increases the accuracy of the simulation carried on by the model embedded in the algorithm...
Due to the current demand for faster and large number of satellite realization, test bed plays the fundamental role for developing high fidelity space systems. Our work is based on a new test system architecture called Modular Test System (MTS) architecture for rapid realization of on-board computer (OBC) packages. This envisages standardization, miniaturization, easy re- workability, greater portability...
The main idea of plug and play process control is to initialise and reconfigure control systems automatically. In this paper these ideas are applied to a scaled laboratory model of a district heating pressure control system. First of all this serves as a concrete example of plug and play control, secondly some of the first techniques developed for these problems are demonstrated by experiments. The...
This work considers the problem of fault detection and isolation (FDI) and fault-handling for networked systems subject to actuator faults. The faults considered preclude the possibility of nominal operation in the affected unit. First, a model-based methodology is presented to detect and isolate faults with the explicit consideration of uncertainty. Then, an algorithm is developed to generalize the...
This paper describes the calculation of the elements that are part of the system that controls automatically the temperature in the furnace with rotary hearth, the calculation of the furnace efficiency and of the maximum value of the disturbance that occurs in the process. We also suggest a circuit to control automatically the temperature in all the 5 sectors of the furnace, considering their interinfluence.
Rapid thermal processing (RTP) of semiconductor wafers involves processing single wafers in small reaction chambers. Powerful lamp arrays are used to heat wafers quickly. The nature of RTP makes control of wafer temperature a difficult problem; ensuring near-uniform temperature across the wafer is critical. After a brief introduction to RTP and the RTP temperature control problem, this paper presents...
Robust multivariable control strategies based on H??-minimization are developed for a pilot plant distillation unit consisting of two coupled distillation columns for the separation of the mixture Methanol/Ethanol/n-Propanol. A comparison is made between several control strategies in nonlinear simulation and experiment. Controller design is based on transfer function matrices describing column dynamics...
