In this paper, Maclaurin expansion and Padé approximation are utilized to handle the RHP zeros in the simplified decoupling control and the choosing strategy is given. To improve the robustness of each loop, Active Disturbance Rejection Control (ADRC) is adopted as a good solution which can estimate and compensate the total disturbances by the extended state observer (ESO). Besides, the stability...
In echo-based audio watermarking methods, poor robustness and low embedding capacity are the main problems. In this paper, we propose a novel time-spread echo method for audio watermarking, aiming to improve the robustness and the embedding capacity. To improve the robustness, we design an efficient pseudonoise (PN) sequence and a corresponding decoding function. Compared to the conventional PN sequence...
With sustained growth of intermittent power supplies connected to grid, the randomness and volatility of intermittent power supplies will bring new challenges to power system optimization dispatch. For dealing with the uncertainty of large-scale intermittent power supply, this paper introduces robust optimization theory into optimization dispatch for hybrid wind/photovoltaic/hydro/thermal power systems...
This paper proposed robustness study in the dual-rotor continuous mixer control system. Based on an in-depth and comprehensive study on the control system including hardware and software, system architecture was realized and main results were attained: (1) According to the working environment and functional requirements, the appropriate software and hardware were selected, and the control system structure,...
