Summary
Efficiency of the model reference based adaptive control systems is investigated and discussed in this master degree work. The main goal of this work was to evaluate and compare the performance characteristics of two widely used in mechatronics adaptive control approach – adaptive control approach based on controller parameters automatic adjustment (parameter adaptive approach) and adaptive control approach based on compensating control signal generation (signal adaptive control). Investigations were carried out on the model of the second order electromechanical velocity control system, realized with help of matlab/simulink software. Transmittance of the reference model is coincident with transmittance of conventional hierarchically arranged velocity control system, adjusted in respect of quantitative optimum conditions.
The rapidity of adaptation process in the case of velocity controller detune or control object parameters change, the limits and velocity of system parameters drift and influence of external load on adaptation process were investigated for both – parameter adaptive and signal adaptive control systems cases. For obtaining of continue adaptation process, the harmonious reference and loading signals were applied on the system. The system parameters change was also modeled in harmonious mode.
The modeling results allow comparing the performance characteristics of these both adaptive control methods. It was demonstrated in this work that signal... [to full text]
