Abstract
Phase lag is common in the heading system of unmanned surface vessels (USVs). This paper presents a general design method for combining sliding-mode control with U-control-based active disturbance-rejection control (UADRC). By introducing a nonlinear term, the model can reveal the differential equation of the system control error as a general convergence law in sliding-mode control. Simultaneously, the sliding-mode control law with a fast convergence speed is presented for system errors. The numerical simulations showed that the UADRC had smaller phase lag, a faster response speed, and fewer fluctuations, thus verifying the effectiveness of the proposed method in reducing phase lag.
期刊介绍：
Control Engineering Practice strives to meet the needs of industrial practitioners and industrially related academics and researchers. It publishes papers which illustrate the direct application of control theory and its supporting tools in all possible areas of automation. As a result, the journal only contains papers which can be considered to have made significant contributions to the application of advanced control techniques. It is normally expected that practical results should be included, but where simulation only studies are available, it is necessary to demonstrate that the simulation model is representative of a genuine application. Strictly theoretical papers will find a more appropriate home in Control Engineering Practice''s sister publication, Automatica. It is also expected that papers are innovative with respect to the state of the art and are sufficiently detailed for a reader to be able to duplicate the main results of the paper (supplementary material, including datasets, tables, code and any relevant interactive material can be made available and downloaded from the website). The benefits of the presented methods must be made very clear and the new techniques must be compared and contrasted with results obtained using existing methods. Moreover, a thorough analysis of failures that may happen in the design process and implementation can also be part of the paper.
The scope of Control Engineering Practice matches the activities of IFAC.
Papers demonstrating the contribution of automation and control in improving the performance, quality, productivity, sustainability, resource and energy efficiency, and the manageability of systems and processes for the benefit of mankind and are relevant to industrial practitioners are most welcome.
