The traditional control architecture, designed for continuous measurement, is inadequate to address the constraints posed by the fragility of facilities in harsh maritime conditions. Therefore, it is necessary to enhance the transient stability performance in non-ideal conditions and environments. This work proposes a novel intermittent predefined-time control algorithm. This approach eliminates the need for frequent measurement and recalculation of control laws at every moment, and extends the usage scenarios of intermittent control from first-order systems to second-order systems. During the holding interval, the control input remains as the last control signal in the driving interval, provided that the validated stability conditions are satisfied. The designed controller also ensures stability with zero control inputs during the holding interval. Furthermore, the proposed method aims to optimise energy consumption in control and measurement. Using the Lyapunov theorem and mathematical induction, sufficient conditions for achieving predefined-time convergence in intermittent control are derived and verified with unmanned vehicles. The proposed method demonstrates a 5.4% reduction in tracking error compared to the fixed-time control method, and a 7.9% reduction in tracking error compared to the event-triggered predefined-time control method. This approach reduces the frequency of control law recalculations, measurements and energy consumption.</p>","PeriodicalId":50382,"journal":{"name":"IET Control Theory and Applications","volume":"19 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/cth2.70079","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145271760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key innovation lies in the integration of a super-twisting barrier function based adaptive sliding mode control (ST-BFASMC) with a radial basis function neural network (RBFNN) observer, achieving simultaneous improvements in convergence speed and fault tolerance. Firstly, a RBFNN observer with weight and centre value update strategy is designed. Secondly, a non-singular fast terminal sliding surface and control law with a super-twisting term are constructed. Furthermore, the fixed-time convergence properties of both the controller and observer are rigorously proven using Lyapunov stability theory. Experimental studies on quadrotor UAV attitude control demonstrated that the adopted RBFNN observer achieved over 60% improvement across all performance metrics compared to baseline methods, while the control algorithm exhibited more than 30% enhancement in multiple indicators relative to conventional ASMC and barrier function based ASMC (BFASMC) approaches.

One enabling the robot to guide human motion using tracking control, and the other allowing it to follow human motion via admittance control. Both frameworks incorporate adaptive algorithms to estimate interaction forces, which are then integrated into controller designs to enhance performance and adaptability. In the first framework, the estimated forces are used to compensate for human-applied forces, enabling the robot to accurately follow a predefined trajectory. In contrast, the second control framework uses the estimated forces to adjust the robot's reference velocity, aligning its motion to human intentions.

Although the PID controller is widely used in UAVs due to its versatility and functionality, it has precision and disturbance rejection limitations. The discrete-time fractional-order PID (FOPID) controller is a valid alternative for UAV control that requires approximating the integral and derivative terms using an infinite summation of fractional terms, from which the most representative are selected for practical implementation. For low-scale UAV models, implementation is challenging since microcontrollers must process fractional operations in discrete time into limited hardware capabilities. In this context, tuning control parameters also represents a challenge since the PID constants and the fractional order parameters must be considered. This study proposes a discrete-time FOPID controller emphasizing the integral term, utilizing the same components as a conventional FOPID but with improved tuning flexibility. Since the integral term plays a key role in reducing tracking errors, this approach enhances accuracy without significantly increasing computational complexity, ultimately resulting in an FOPI + D controller.

Experimental tests were conducted on the 1D-TRS using different reference signals, such as step, steps, and ramp inputs. Additionally, external disturbances were introduced during experimental scenarios. The proposed controller was compared against traditional PID and discrete FOPID controllers, with performance metrics demonstrating improved system response. The results showed that the proposed controller enhances trajectory tracking in 1D-TRS, improving both precision and robustness against disturbances.
