A FAS approach for stabilization of generalized chained forms: part 1. Discontinuous control laws

Science China(Information Sciences) 2024年第2期67卷 118-143页

In this paper, a type of general nonholonomic systems is proposed, which contains both the Brockett's two example systems, and their extended n-dimensional chained forms, as special cases. For the stabilization of such systems, a stabilizing controller is proposed based on the fully actuated system(FAS)approach, which is discontinuous at the origin but time-invariant when the open-loop system is time-invariant,and drives the feasible trajectories of the system to the origin exponentially. Furthermore, the proposed FAS approach is also extended to the sub-normal system case and the time-delay system case.

The optimization of equipment system combination is crucial for the pre-deployment decision-making of our military. In order to obtain advantageous equipment portfolio solutions, we establish a multi-layer network optimization model for equipment systems and introduce a novel multi-objective optimization algorithm for equipment portfolios in combat systems. Firstly, a multi-objective optimization model for equipment system combination recommendation is established, with the objective of optimizing combat network redundancy and vulnerability. Secondly, due to the complexity of the equipment system optimization model and the challenge of finding optimal equipment portfolios, we propose a clustering-assisted preselection multi-objective evolutionary algorithm called MECAP. This algorithm is designed to enhance the convergence of the population towards the optimal solution set. Additionally, the experimental results highlight the benefits of applying MECAP for offspring generation strategy after model sampling. © 2024 ACM.

This paper investigates the robust bounded-H8 stabilization for a class of high-order fully actuated systems (FASs) with time-varying uncertainty and disturbance. Based on the FAS approaches and the H8 control, a robust bounded-H8 controller is designed, which guarantees that the system state and its derivatives of each order are globally bounded. Furthermore, a combined disturbance, composed of part time-varying uncertainty and disturbance, is given. With the help of the combined disturbance, the impact of the uncertainty and the disturbance on system output can be attenuated simultaneously, because the closed-loop high-order FAS has the bounded-H8 performance. A simulation example is provided to demonstrate the effectiveness of the proposed control method. © 2024 IEEE.

In this paper, we introduce a novel time-delay approach for sampled-data bounded extremum seeking (BES) targeting single-variable static quadratic maps. This approach provides a streamlined and less restrictive analysis of practical stability. Assuming that the Hessian H is within a known range, we employ a time-delay approach to averaging to convert the original sampled-data BES system into a time-delay system. This transformed system represents a perturbation of a neutral type system with fixed coefficients. We further describe this system using a linear ordinary differential equation (ODE) framework and utilize the variation of constants formula for analyzing its practical stability. We establish conditions, presented as simple scalar inequalities that rely on tuning parameters, to guarantee the practical stability of the sampled-data BES control system. This new method simplifies the conditions for stability and improves results compared to the traditional Lyapunov-Krasovskii (L-K) technique. The efficiency of the new approach is demonstrated by an example. © 2024 IEEE.

This paper deals with the problem of intercepting maneuvering targets with terminal angle constraints for missiles subjected to three-dimensional non-decoupling engagement *** achieve the finite-time interception and satisfactory overload characteristics, a time varying sliding mode control methodology is developed based on a time base generator function. The main feature of the proposed guidance law guarantees the Line-of-Sight(LOS) angles to converge to small neighborhoods of the desired values at the interception time. First, a fractional power extended state observer is used to estimate the unknown target acceleration, which can significantly reduce the adaptive switching gain. The fractional power extended state observer enjoys the advantage of better noise tolerance. Then, a newly designed sliding mode surface is constructed by introducing a time base generator function and the time-varying sliding mode guidance law is developed based on this time-varying sliding surface. The proposed guidance law significantly reduces the overload magnitudes. Numerical simulations are carried out to verify the performance of the proposed guidance law.

A FAS approach for stabilization of generalized chained forms: part 2. Continuous control laws

In this paper, continuous time-varying stabilizing controllers for the type of general nonholonomic systems proposed and treated in part 1 are designed using the fully actuated system(FAS) approach. The key step is to differentiate the first scalar equation, and by control of the obtained second-order scalar system, a proportional plus integral feedback form for the first control variable is obtained. With the solution to this designed second-order scalar system, the rest equations in the nonholonomic system form an independent time-varying subsystem which is then handled by the FAS approach. The overall designed controller contains an almost arbitrarily chosen design parameter, and is proven to guarantee the uniformly and globally exponential stability of the closed-loop system. The proposed approach is simple and effective,and is demonstrated with a practical example of ship control.

This paper is concerned with an output tracking problem for a type of discrete-time high-order fully actuated (DTHOFA) systems, especially improving the dynamic performance of the tracking control. An improved predictive tracking control approach is investigated to address this problem. For the improvement of dynamic performance, an attempt of this approach is to introduce an increment of output predictions into an objective function of predictive control, such that the changes of output predictions can be limited to suppress the oscillation of output responses. To ensure the full actuation feature, an incremental HOFA prediction model is developed by means of a Diophantine Equation to substitute for a first-order prediction model. Through this prediction model, the multi-step ahead output predictions and their increments are obtained to optimize the objective function involving the tracking control performance and the improvement of dynamic performance. The in-depth discussion derives a sufficient and necessary condition for the stability and tracking performance of closed-loop DT-HOFA systems. To verify the feasibility and superiority, the proposed result provides a solution to the tracking control of RLC circuit. © 2024 Technical Committee on control theory, Chinese Association of Automation.

This article delves into a data-driven approach for solving the adaptive optimal output regulation problem in continuous-time linear systems with uncertain dynamics. Employing a class of parametric Lyapunov equations in conjunction with a nominal system model, the initial stabilizing feedback gain is determined to initiate the iterative method. Then, by utilizing a policy-iteration-based technique, we design an optimal control policy to achieve precise output tracking and disturbance rejection. The prescribed convergence characteristics of the closed-loop system directly result from the properties embedded within the solution of the parametric Lyapunov equation. The applicability and performance of the proposed method are demonstrated through a numerical example involving an input-constrained double integrator system. © 2024 SPIE.
