| Abstract [eng] |
Specific dynamic behaviors of astatic objects affect selection of the control systems structure, control principle and tuning method. The goal of this final work is to investigate and compare different structures of control systems work quality indicators of astatic objects. It will be done using simulation way by following the setpoint and compensating disturbance effects. There has been investigated automatic control system of astatic objects. In this system has been installed additional feedback, which transforms astatic objects to stable in the open loop. System work investigation has been accomplished in simulation way (MATLAB/Simulink environment) by comparing control system with additional feedback and typical one feedback automatic control system. For the system work investigation there were selected 4th rows with different dynamic behaviors which describe the astatic objects having transformation function with time delay. Control systems working quality indicators were evaluated by modeling system response to the hopping setpoint and disturbance changes. System controllers were coordinated for aperiodic and for transitions processes with 20 % relative dynamic deviations. There were made statistical evaluation and comparison of the quality indicators by comparing: override, regulation and rising time. Complete analysis of the results contains recommendations for the design of astatic objects control systems. |
