A Simulated Annealing Controller for Sloshing Suppression in Liquid Transfer with Delayed Resonators

Abstract

A simulated annealing controller for sloshing suppression during the transfer of a liquid using a vehicle with active and passive vibration absorption is proposed. The proposed design technique aims to suppress sloshing induced by vehicle vibrations due to force disturbances applied on the liquid carrying vehicle due to road surface unevenness, while dealing with practical problems like the lack of measurements of the liquid's motion within the tank. Active vibration absorption is achieved with the use of a couple of Delayed Resonators. Despite the high complexity of the system's model, the proposed technique results in an easy to implement linear static measurement output feedback controller with satisfactory performance with respect to sloshing suppression.

A three term controller for ride comfort improvement

“…[1]- [14] and the references therein) as well as for industrial applications where safe and accurate transportation of industrial goods is of vital importance (see e.g. [15]- [16] and the references therein). In the literature, several control strategies have been proposed to achieve the above design requirements, ranging from semi-active controllers to intelligent controllers.…”

Velocity control and vibration attenuation for a cart-pendulum system with Delayed Resonators

“…Using this approximation different control methods have been proposed (see [5], [6] and [9]). Active control methods that actuate the rotational motion of the tank have been proposed in [1], [5], [10] and [11]. Furthermore, in [11], active vibration absorption with delayed resonators has been used for sloshing suppression during liquid transfer in a tank mounted on a vehicle.…”

“…For much more details in delayed resonators see [12]- [14]. In [11] the robustness of the control scheme introduced in [10], is studied taking into account simultaneous wear to the front and rear springs of the resonators. In the present paper, a cart similar to that presented in [10] and [11], is considered to carry a freely rotating pendulum, approximating the movement of a liquid inside a tank that is firmly attached to the cart.…”
