Description

technical field [0001] The invention belongs to the technical field of servo control, and in particular relates to a crystal grinding control method and system based on open-loop cross-coupling iterative learning. Background technique [0002] With the development of science and technology and industry, grinding is developing towards high speed, high precision and high productivity. Glass processing is also developing towards CNC mechanization, but due to the particularity of glass materials, edge wear and surface smoothness are all issues that need to be considered during processing. In the fields of CNC machining, robot control and high-precision machining, permanent magnet synchronous motors have extremely important applications. Because the mathematical model of permanent magnet synchronous motor is a nonlinear, strongly coupled multivariable system, it cannot fully adapt to high dynamic performance speed control systems or servo systems Contents of the invention [...
