6 results about "Control reconfiguration" patented technology

Control reconfiguration is an active approach in control theory to achieve fault-tolerant control for dynamic systems. It is used when severe faults, such as actuator or sensor outages, cause a break-up of the control loop, which must be restructured to prevent failure at the system level. In addition to loop restructuring, the controller parameters must be adjusted to accommodate changed plant dynamics. Control reconfiguration is a building block toward increasing the dependability of systems under feedback control.

A linear active disturbance rejection control method combined with a variable step size adaptive filter

To solve the problems of traditional virtual synchronous generator (VSG) such as insufficient disturbance rejection ability, noise sensitivity and limited dynamic performance under complex working conditions, a control strategy combining linear active disturbance rejection control (LADRC) and improved adaptive filter algorithm is proposed. By establishing the equivalent model of VSG, virtual inertia and droop control are introduced to reconstruct the operation characteristics of inverter synchronous generator. LADRC is used in the voltage loop to estimate and compensate the internal and external disturbances of the system using the extended state observer, thereby improving the robustness of the system. To solve the noise amplification problem caused by the increase of the observer bandwidth, an LMS adaptive filter is introduced to preprocess the error signal, and a variable step-size LMS algorithm based on the optimized Sigmoid function is used to balance the convergence speed and steady-state accuracy. Finally, a "VSG+LADRC+improved LMS" integrated control architecture is constructed. The simulation and experimental results show that the proposed method significantly improves the disturbance rejection ability and dynamic response under off-grid and on-grid switching and load disturbance, and has good engineering application value.
