Abstract:Pri izvedbi tega dela nam je bilo osnovno vodilo zasnovati splošno uporaben »online« adaptivni mehki regulator, ki bi mu parametre bilo možno spreminjati med samim delovanjem, algoritem pa bi bil realiziran s pomočjo nizkocenovnega industrijskega krmilnika. V preteklosti preizkušeno profesionalno programsko orodje za načrtovanje mehkih regulatorjev Siemens FuzzyControl++ namreč kljub visoki ceni ne omogoča načrtovanja adaptivnih regulatorjev, spreminjanje parametrov je možno le pri zaustavljenem procesorju, povrhu pa je uporabno le za sedaj že zastarele krmilnike višjega cenovnega razreda Siemens serije S7-300 in S7-400. Preizkusi so bili izvedeni za primer regulacije nivoja vode v rezervoarju na t. i. modularni proizvodni postaji za procesno avtomatizacijo proizvajalca Festo. Naloga predstavlja tudi SCADA-uporabniški vmesnik Siemens WinCC za nadzor vodenega procesa in spreminjanje parametrov vodenja med samim delovanjem. Učinkovitost zasnovanih mehkih regulatorjev je bila primerjana s klasičnim PI-regulatorjem in s PI-regulatorjem Siemens PID Compact z integrirano funkcijo za »offline« samonastavitev parametrov.

Title:Control design of nonlinear control plant with adaptive controller based on combination of fuzzy logic and gradient optimisation technique
Abstract:The basic principles of our work to design a generally applicable "on-line" adaptive fuzzy controller are next: to change the parameters during operation and the algorithm would be realized with the help of low-priced industrial controller. In the past, proven professional software tool for designing fuzzy controllers Siemens FuzzyControl ++, despite the high price, doesn't allow the design of adaptive controllers, changing parameters is possible only when the processor is stopped, and on top of that, it is only useful for the now obsolete industrial controllers high-priced Siemens S7-300 and S7-400 series. Tests were carried out for control plant: the water level in the tank at so called modular manufacturing station for process automation from Festo company. The SCADA user interface Siemens WinCC for process control and management parameters change during operation are also presented. Efficiency of presented fuzzy controllers were compared with a conventional PI controller and PI controller Siemens PID Compact with integrated function for the "off-line" parameter self-adjusting.
Keywords:adaptive fuzzy controller, gradient adaptation procedure, fuzzy controller of reference value
