Research on fuzzy PID-RBF cooperative control of variable-frequency drives based on TMS320F28335

Abstract： To improve the response and robustness of variable-frequency drives under load changes and parameter drift, a tunable resistance-capacitance control circuit based on TMS320F28335 is developed. A cooperative strategy uses fuzzy PID as the main controller and an RBF network to compensate nonlinear residuals. Tests showed that, under a load step, the response time decreased from 210 ms to 96 ms and the steady-state error from 4.6% to 1.7%. Also, in the presence of parameter disturbances, the response time was shortened from 260 ms to 120 ms and the error decreased from 5.2% to 2.1%. Compared with fuzzy PID alone, the cooperative controller further reduces the error and speed fluctuation respectively by 30% and 30.6% under parameter disturbance, confirming the contribution of RBF compensation regarding model mismatch and nonlinear residuals.
