Unstable object parameters estimation with one input and two outputs in automatic control system

摘要

The inverted pendulum on the cart which has one input and two outputs is an unstable object. Unstable object parameters estimation assumes the active method of identification. The initial angular situation of a pendulum is set, in this case 0.7 radian, and the pendulum corner measurement and the cart position definition is performed further. It gives three numbers - three amplitudes values. Thus, it is necessary to establish connection between the object parameters and the transition processes amplitudes values measured at some points in time. The special tables and nomograms are formed on the basis of the measurements executed as the result of the regulation system modeling. It is simple to determine the identified object parameters by these tables and nomograms.
