A double-loop framework is established. The kinematic governor employs model predictive control(MPC), which takes into account the UUV’s kinematic characteristics as well as the conditions for obstacle avoidance when calculating the control command and provides an optimal velocity command input for the dynamic controller. Then, the dynamic controller is developed based on a fast finite-time extended state observer (FESO) and a fast adaptive integral terminal sliding mode controller (FAITSMC). The construction of the fast FESO integrates UUV’s dynamics model, a proportional integral velocity variable, and a fractional order term of the output observation error, which can identify model uncertainties and external disturbances in finite time. By means of adaptive uncertainty compensation, the FAITSMC enables the error between actual speed and speed reference to converge to a minimum quickly. By applying Lyapunov stability theory and the finite-time analysis technique, sufficiency criteria are established to guide and keep the UUV on a reference trajectory via an inner-outer loop control structure.

Current technologies control the attitude state variables of the vehicle typically at 0° to maintain the car body at a horizontal inclination. However, in complex terrains, the centre of gravity needs to be elevated to improve passability or reduce the centre of gravity to increase driving stability. During steering or braking, the pitch or roll angle of the body needs to be actively changed to improve the gripping force and reduce the possibility of rollover. This study considered the non-linear characteristics of shock absorbers and exploited the advantages of the active disturbance rejection technology, such as high tracking efficiency and small overshoot, to achieve stable tracking. The stability of the tracking attitude angle is analysed within the Lyapunov framework. Simultaneously, a linear suspension attitude-tracking control algorithm is designed as a linear quadratic regulator (LQR) for verifying the tracking control performance of the FWLV. The accuracies of the two algorithms were compared under stationary state, single-side sinusoidal, and random pavement conditions through simulations and vehicular tests. The results indicate that the stability of the attitude-tracking values by ADRC is better than that by the LQR. In addition, comparisons between the simulations and tests illustrated the validity of the active attitude-tracking system.</div></div>","PeriodicalId":17283,"journal":{"name":"Journal of The Franklin Institute-engineering and Applied Mathematics","volume":null,"pages":null},"PeriodicalIF":3.7,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142420759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
