However, most of the related works often focus on slow movements only suitable for regular tasks in well-structured environments. This motivates us to propose a highly robust control scheme designed specifically for UAV aggressive maneuvers, encoded by rapid and large changes in either position or attitude. The core of our approach is the data-informed incremental dynamics and the quaternion facilitated control scheme. The former facilitates the model-free control that eliminates the requirement to model the complex dynamics at high velocities and accelerations accurately; While the latter avoids potential singularities during large angular changes. In particular, we first utilize one-step-backward data to construct incremental dynamics, a model-free representation of the UAV dynamics. Then, the constructed incremental dynamics serves as the basis for the development of both position-priority and attitude-priority control schemes, wherein the novel quaternion based aggressive maneuver tracking controllers are designed with complete theoretical analysis. The aggressive maneuvers such as roulette, barrel roll, multiple-flip and cobra maneuvers are chosen for tri/quad/hexa/octocopter platforms to evaluate the performance of our proposed position-priority and attitude-priority control schemes, during which the linear velocity up to <span></span><math>\u0000 <semantics>\u0000 <mrow>\u0000 <mn>20</mn>\u0000 <mspace></mspace>\u0000 <mtext>m/s</mtext>\u0000 </mrow>\u0000 <annotation>$$ 20kern0.3em mathrm{m}/mathrm{s} $$</annotation>\u0000 </semantics></math>, the angular changes up to <span></span><math>\u0000 <semantics>\u0000 <mrow>\u0000 <mn>360</mn>\u0000 <mo>°</mo>\u0000 </mrow>\u0000 <annotation>$$ {360}^{{}^{circ}} $$</annotation>\u0000 </semantics></math>.</p>\u0000 </div>","PeriodicalId":50291,"journal":{"name":"International Journal of Robust and Nonlinear Control","volume":"35 9","pages":"3856-3865"},"PeriodicalIF":3.2,"publicationDate":"2025-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143914670","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}

From the perspective of an attacker with limited energy, our objective is to find the optimal trade-off between energy allocation and channel coverage. If the attacker allocates more energy each time, the packet loss rate of the channel increases, leading to a decrease in system performance. Our contributions are threefold. First, the stability conditions of PSS are provided based on the initial values of prior estimation errors in both specific and general cases. Second, we give system stability conditions in the presence of an external attacker, for the case that the relay node adopts the Direct Forwarding Strategy (DFS). Finally, the attack strategy optimization is cast as a Markov decision process (MDP) problem.

In order to save the communication resources of the system and reduce the computational amount, we consider the ET method to reduce the number of controller updates by designing the static event-triggered (SET) condition and the DET condition, respectively, and comparing the simulation results, we find that the DET further reduces the frequency of the controller update on the basis of SET. In addition, if the Bernstein theorem is used to compensate for the unknown non-linear function directly, we need to derive the coefficients of the Bernstein polynomials through mathematical derivation, but we believe that the non-linear dynamic function is unknown, so we cannot directly use the Bernstein polynomials to approximate the unknown non-linear dynamic function, in order to solve the problem that the coefficients of the Bernstein polynomials are uncertain, we deal with the uncertain parameters in the Bernstein polynomials by an adaptive strategy to ensure that the Bernstein polynomials approximate the unknown non-linear dynamical system and guarantee that all signals in the closed-loop non-linear dynamical system are semi-global uniform ultimately bounded (SGUUB).
