Study Of Characteristic And Realization Of The Platform Of Anti-rolling Tank

The anti-rolling tank is one of the most popular used stabilizing equipments, and it fits for ships working at zero speed or low speed such as passenger and train ferry, roll-off vessel, research and exploration vessel and so on in particular. It can be classified as U-tube tank stabilizer and flume anti-rolling tank according to structural configuration, and the former one has three types, namely passive, active control and controlled passive tank in terms of the control mode.The examination platform of anti-rolling tank is an important experiment facility to research and design anti-rolling tank. As the platform can simulate factual movement of the vessel, it is suitable to study the movement and the control rule of the tank, as well as measure stability efficiency. The device is a kind of special complex system. So far the country has no such examination equipments as so large scale.The examination platform of anti-rolling tank is based on the roll model and conform connection of ship, it can simulate some ships from 0.5 to 100 thousands tons. In practice, it is necessary to verify whether the platform can simulate the given ship parameters precisely, this is count for much to the design rationality of the tank directly. So this paper do some elaborate tests to the parameters and data of the platform firstly, also analyze and study the trait of it embedded.This paper designed a kind of PID parameters self-tuning controller based upon blur control. The biggest advantage of blur control is that it's not depend on the accurate mathematics model, can get over the influence of non-linear, as well as have excellent robustness to parameter exchange of adjust object. Combine blur control with general PID control, on line self-adjusting PID parameters according to different error and error variety-rate, which is called PID parameters self-tuning blur controller. The new one not only have agility and good robustness of blur control but also possess high precision of PID controller. The simulation results show that this kind of control strategy is effective.In addition, this paper studied simulation method of irregular waves and its realization in the system, did some analyses to the simulation results, and provided roll moment simulation of three kinds of ship. Demarcate and debug the hardware circuit and sensor again, and broaden the output range of power amplifier circuit. Overcome the sway asymmetry of tracking regular waves due to the servo valve's deflection via software method.At last, the paper presented the experiment results of the examinationplatform,of anti-rolling tank. The results indicate that the platform can simulate the ship's roll motion well and these productions have important sense to the design of anti-roll tank and simulation of platform.
