- Abstract:
-
In order to make closed-loop vector control system work in the best status, a hybrid tuning method was introduced, which combines a model-based offline tuning method with a fuzzy PI online tuning method. First of all, the mathematical model of the system was constructed in accordance to the vector control theory, and the moment of inertia was calculated using the method of a constant-torque startup and freely stopping system. After that the PI parameters and the inner loop compensations were calculated according to the mathematical model. Next, a fuzzy PI controller was structured, and the new PI control rule forms were put forward. The final contrastive experiments indicate that the hybrid PI parameters tuning method improves the dynamic performance and the steady-state precision of the system, and it is better than the system which only adopts a single tuning method. The validity of the method was justified.
