The utility model provides a double-pendulum swing, which belongs to the mechanical technology field and solves the technical problems of poor safety and poor enjoyment of the traditional swing. The double-pendulum swing comprises a support bracket, two first pendulum rods and two second pendulum ...
The actions of a double pendulum have been studied for many years, especially in relation to the swing of a golf club. The physics of swinging a tennis racquet has not been studied in nearly as much detail. Part of the problem is that there are many different ways of swinging a racquet...
Brief paper: Swing-up of the double pendulum on a cart by feedforward and feedback control with experimental validation The swing-up maneuver of the double pendulum on a cart serves to demonstrate a new approach of inversion-based feedforward control design introduced recent... K Graichen,M ...
Neuro-fuzzy controller based on Adaptive Neuro-Fuzzy Inference System (ANFIS) is proposed for swinging up a double pendulum from its hanging position to the inverted position. The controller is designed through two stages. In learning stage, the controller, which is an inverse mapping model from ...
Based on the low-pass filter, the system response law of the double pendulum system hoisting DMB is analyzed. On this basis, combining the time optimal anti-swing control and the first-order low-pass filter, the improve time optimal anti-swing control is proposed. And the velocity trajectory...
Tower crane system is usually considered as single-pendulum system to design controllers. However, in reality, tower crane often exhibits more complex double-pendulum characteristics, which makes it more difficult for positioning and swing angles elimination. To this end, a composite trajectory planning...

Swing-up control of a serial double inverted pendulum A swing-up control scheme for a serial double inverted pendulum is proposed. The control scheme is to swing up the pendulum in three steps, step 1: to swin... T Henmi,M Deng,A Inoue - American Control Conference 被引量: 44发表: 20...
banked by the pendulum swing of the morning’s tide, and the soft dust of dry sand over my footprints. Oystercatchers pleep at the water’s edge . as the sun winds down another day and the light from the Bell Rock ticks the seconds by ...
Figure 7 shows the swing angle of the bottom pendulum mass, 𝜃2θ2, along the time of the path achieved by the MPC-PD control system. The maximum value is 𝜃2=0.23θ2=0.23 rads. Figure 8 shows the evolution in time of 𝜃2θ2 under the PD-PD control system. Its maximum value...
