Abstract

An under-actuated pendulum control experimental apparatus relates to an under-actuated control experimental apparatus applying to academic researches for control theory and control engineering discipline and electron and transmission discipline, is used for solving the problems that experimental apparatus, which is used for the academic researches of non-linear control theory in higher education institutions and scientific institutions, still stays at numerical simulation level, appropriate material system is absent and the theory is disconnected with the practice. The upper I / O terminal and drive I / O terminal on a two-shaft motion control card are respectively connected with the I / O terminal of an upper computer and the I / O terminal of a DC motor driver. The control output terminal of the DC motor driver is connected with the control input terminal of a DC servo motor. The signal output terminals of the DC servo motor and an angle detector is connected with the signal input terminal of the two-shaft motion control card. The output shaft of the DC servo motor is connected with the input shaft of an under-actuated pendulum system by a shaft coupling. The input drive torque of the input shaft of the under-actuated pendulum system is delivered to a double-pendulum output shaft through a synchronous drive system.

Description

technical field [0001] The invention relates to an underactuated control experimental device suitable for the academic research requirements of the disciplines of control theory and control engineering as well as the disciplines of power electronics and electric transmission, and belongs to the technical field of underactuated mechanical system control. Background technique [0002] In the past 50 years, the application of spacecraft and robotic systems has continuously promoted the analysis and control of mechanical systems and nonlinear systems. All along, the development of mechanical systems and nonlinear control theory are complementary and mutually promoting. The analysis of multi-body control problems of mechanical systems and affine control problems of nonlinear systems (such as controllability, observability, etc.) and control design (such as stability, output tracking, etc.) are all theoretical products of this promotion , and the affine control problem has also b...
