Abstract

The invention provides a method for comparing control efficiencies of a tensegrity structure based on input energy of actuators, and relates to the technical field of structural engineering. The method comprises the steps that form finding of the tensegrity structure is conducted; control algorithms for the tensegrity structure are selected; actuator layout schemes are selected; a common target value of control input energy of all the different control algorithms is determined through trail calculation; a weight coefficient is determined; the time domain and frequency domain dynamic response of the tensegrity structure is obtained; control effects are compared and selected; the actuator layout schemes are replaced, the control efficiency coefficients and frequency response functions of allthe algorithms under the actuator layout scheme are obtained, the control efficiencies of the different actuator layout schemes are compared, and thus the optimal control algorithm and the optimal actuator layout scheme are obtained. According to the method, the control efficiencies of the control algorithms in the time domain and frequency domain can be well compared, the control efficiencies ofthe different control algorithms can be compared, the control efficiencies of the different actuator layouts and different numbers of the actuators are obtained, and support is provided for selectionof the actuator layouts and the actuator number.
