An Improved Model-Free Adaptive Control Algorithm Based on Golden Section

MFAC: The controller is designed to utilize only the I/O data of the controlled system. Any information in the controller that does not contain a mathematical model of the controlled process, which is suitable for complex time-delay systems. For time-delay systems, there are many studies on their stability, but there are relatively few studies on their rapidity. Inspired by the classic model-free adaptive control algorithm, two parameters L

and L

with the proportion of golden section are introduced in the parameter estimation control scheme. An improved algorithm is proposed. MATLAB simulation experiments show that the improved algorithm can improve control response speed of the time-delay system. Therefore, the effectiveness of improved control algorithm is proved.
