Problems solved by technology

When searching for the controller parameters corresponding to the minimum performance criterion function, the traditional IFT (Iterative Feedback Tuning, iterative feedback tuning) algorithm usually uses an optimization algorithm similar to the Gauss-Newton method to optimize the parameters. In this method, each iteration The required three experiments and their linear approximation characteristics fundamentally limit the convergence speed of the algorithm, and it is difficult to meet the high-speed characteristics required by precision industries such as permanent magnet synchronous motor position loop control
