Problems solved by technology
When the system fails, such as signal transmission failure or disconnection of one or more units, the entire control system will inevitably lead to performance degradation or even failure
Furthermore, for a group of motion control systems with multiple entities, centralized control is complex and costly to implement, and even if it could be achieved, the resulting system is unsound or ineffective

The invention discloses a cooperative control lifting platform based on multiple direct drive linear motors and a control method for the lifting platform. The lifting platform can adopt the direct drive linear motors of any principles, the number of the motors can be set according to requirements; the end part of each motor serves as a supporting point of a lifting plane, the structure of the multiple supporting points improves the carrying capacity and the balance of a whole system, meanwhile, a pressure sensor can be arranged at each supporting point according to requirements, the stress condition of the lifting plane can be observed, the balance of the lifting plane can be corrected, and the posture can be adjusted according to requirements. The invention further provides communication topological structures suitable for the lifting platform between the multiple motors. According to the communication topological structures, the movement control precision of the lifting platform conforming to actual transportation requirements can be realized. The lifting platform further comprises an adjacent matrix capable of switching communication topologies on line, and therefore the function of switching the communication topologies can be achieved.
Description
technical field [0001] The invention relates to the field of lifting platforms, in particular to a lifting platform based on multiple direct-drive linear motors and a control method thereof. Background technique [0002] In the modern industrial manufacturing and transportation environment, manual handling has been gradually eliminated by the market, and replaced by lifting equipment that saves manpower and financial resources. Whether in production logistics, construction, civil engineering, or in various fields of daily life, lifting machinery is ubiquitous and has become more and more widely used. [0003] At present, lifts mainly include cable lifts and scissor lifts. The principle of the cable lift platform is to pull the wire rope through the rotating motor to generate linear motion. In practical applications, there are problems such as slow commutation speed and energy loss. At the same time, the wire rope is easy to break, and the pulley structure is easy to age, a...
