Özet:

 

This paper proposes several improvements in the minimal controller synthesis  algorithms, which were developed for a class of nonlinear systems with  uncertainties. The major proposition is that only the output feedback is  enough to control some nonlinear systems without an observer while the  existing algorithms require the complete state feedback. Next, the extended  version and the parameter identification technique of the minimal controller  synthesis algorithm are combined in a single method estimating some more  parameters for some known forms of nonlinearities. This is applicable with  or without the improvement of removing the need for using the complete state  feedback. It is proven that the scaling factors in the algorithms can be  variable and different for each component. The algorithms are applicable to  some noncanonical forms of systems. All the propositions and some of the  existing algorithms are generalized in a single form with some options. A  speed-sensorless DC motor control simulation is also included with quite  exaggerated noisy conditions and the results verify that the proposed  modifications make the minimal controller synthesis algorithms  much more  efficient model reference adaptive control algorithms for certain types  of systems. The proposed method, which does not use the speed measurement,  yields fewer ripples than the existing method, which uses the speed  measurement. In addition, the proposed method accurately estimates the armature  resistance and inductance while the existing method fails to do this.
