Electromagnetic suspension adjusting controller

Abstract

The invention discloses an electromagnetic suspension adjusting controller. The electromagnetic suspension adjusting controller comprises a whole vehicle active suspension system and a three-level hierarchical controller constituted by a planning-level controller, a coordination-level controller, and an execution-level controller. By adopting an intelligent hierarchical control strategy, a whole vehicle active energy-regenerative suspension control system is divided into the planning-level controller, the coordination-level controller, and the execution-level controller. The planning-level controller is used to determine moving posture of a vehicle according to various sensor information, and by combining with a whole vehicle active energy-regenerative suspension coordination control logic, the planning-level controller is used for integrated coordination and decision planning of various control sub-systems. The coordination-level controller is used to receive instructions of an upper level, and by taking the feedback information of the execution level as the reference, the coordination-level controller is used for the integrated analysis and decision of the various sub-systems. The execution-level controller is mainly used to execute the control tasks of the three sub-systems. The electromagnetic suspension adjusting controller is advantageous in that defects of a centralized control structure are prevented, and reliability of a system is improved; by adopting the hierarchical type coordination control strategy for the control of the whole vehicle active energy-regenerative suspension, the good integrated performance of the whole vehicle is realized.

Description

technical field [0001] The invention relates to an electromagnetic suspension adjustment controller, which is suitable for layered control of an active energy-feed suspension with adjustable three-stage damping, and belongs to the technical field of automobile energy-saving vibration reduction control. Background technique [0002] In recent decades, controllable suspension systems have received extensive attention from academia and industry. Compared with the uncontrollable semi-active / passive suspension system, the controllable suspension system implements adaptive control of its body characteristics according to the current driving conditions and road conditions of the vehicle, thus improving the ride comfort and handling stability of the vehicle. The key to the active energy-feedback suspension system is the actuator. With the rapid development of electromagnetic damping materials and electronic control technology, and under the influence of the development trend of elec...
