Nowadays, the passivity-based control (PBC) as a nonlinear control method with much superiority has been studied more and more frequently, where it has been successfully used in Grid-Tied Inverters (GTI). Due to the high order characteristics of a LCL-filtered GTI, the PBC control law tends to be complicated, resulting in a difficult selection on control parameters. In this paper, a novel PBC parameters design strategy based on the expectant limited steady-state error is proposed. Simulation platform was built in MATLAB/Simulink and a 3-kW experimental device was carried out with DS1202 to verify the correctness and effectiveness of the proposed strategy.

This paper analyses the mathematical model and control strategies of a Hybrid Active Power Filter with Injection Circuit (IHAPF). The control strategy based on the load harmonic current detection is selected. A novel control method for a IHAPF, which is based on the analyzed control mathematical model, is proposed. It consists of two closed-control loops. The upper closed-control loop consists of a single fuzzy logic controller and the IHAPF model, while the lower closed-control loop is composed of an Adaptive Network based Fuzzy Inference System (ANFIS) controller, a Neural Generalized Predictive (NGP) regulator and the IHAPF model. The purpose of the lower closed-control loop is to improve the performance of the upper closed-control loop. When compared to other control methods, the simulation and experimental results show that the proposed control method has the advantages of a shorter response time, good online control and very effective harmonics reduction.
