Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing.

[0019] Such as figure 1 As shown, the low-power control system consists of a current sensor, a PID controller, a smith predictor, a feed-forward controller, a power amplifier, and a controlled object. The working principle of the control system is that the current sensor detects the current, and the detection result is used as the input variable of the pid controller. After the variable is processed by the pid controller, the current signal is output. The signal is output by the power amplifier module to control the current to drive the magnetic bearing to achieve low voltage. Power Control. When a disturbance occurs, the feed-forward controller finds the disturbance and compensates the disturbance to counteract the influence of the disturbance. In the case that the disturbance cannot be completely offset, since the smith predictor offsets the time-delay characteristics o...

Abstract

The invention discloses a vehicle flywheel battery suspension control system for suppressing gyro effect and with low energy consumption. The vehicle flywheel battery suspension control system comprises a low-energy consumption control system and a gyroscopic effect suppression control system. In the low-energy consumption control system, a current sensor reads a control current as input of a PIDcontroller, the control current is regulated by the PID controller and amplified by a power amplifier to control a magnetic bearing rotor to achieve low power operation, when disturbance occurs, a feedforward controller changes the control amount according to the disturbance to offset the influence of the disturbance, a smith predictor estimates the dynamic effect caused by the disturbance entering the system, and the estimation result is fed back to the PID controller to allow the PID controller to change for compensation in advance for the disturbance. In the gyroscopic effect suppression control system, detection signals are subjected to a displacement sensing module, is sent to the PID controller for decoupling to eliminate coupling items and are converted to a current through a force/current conversion module, the current is amplified to control the smooth operation of the magnetic bearing, and when the PID controller cannot perform regulation, the feedforward controller performsregulation to weaken the disturbance or eliminate the disturbance.

Description

technical field [0001] The invention belongs to the technical field of control, and in particular relates to a control system of a magnetic suspension bearing (magnetic bearing). Background technique [0002] Magnetic levitation technology is a new type of support technology that uses magnetic force to suspend objects in space so that it has no mechanical contact with other objects. It has the advantages of no friction, no wear, no lubrication and sealing, high speed, high precision and long life. With the development of electronic technology, magnetic levitation technology has also been developed accordingly, and has been widely used in transportation, aerospace, machinery manufacturing and other fields. [0003] The vehicle flywheel battery is a new type of battery based on magnetic suspension bearing technology. Compared with traditional chemical batteries, flywheel batteries have the characteristics of strong energy supply, long life, environmental protection and no pol...
