Using deflection velocity as a switching signal, a piecewise affine (PWA) model of the CDC suspension system is developed to describe the nonlinear behavior of the damper. Given that the deflection velocity signal is typically not directly measurable in engineering applications and can only be obtained inaccurately through signal processing of existing sensor data, an asynchronous observer is designed based on the given system model.

Existing research on platooning has primarily concentrated on longitudinal control in highways or dedicated road environments. However, these approaches can significantly reduce platooning performance during scenarios requiring lateral maneuvers, such as cornering or obstacle avoidance. To address these limitations, this study proposes a comprehensive platooning system that considers both longitudinal and lateral dynamics. The proposed platooning approach comprises model predictive control (MPC)-based path planning incorporating the constant time gap (CTG) strategy, and integral control-based path tracking. The MPC-based path planning is formulated as an optimal control problem aimed at minimizing the total cost, which includes the candidate path cost based on CTG policy-generated velocity commands and environmental costs. The optimal control input is obtained using particle swarm optimization (PSO), resulting in the generation of an optimal path. For path tracking, an integral error for yaw rate is defined, and an integral control-based method is employed, considering the differential equation of the integral error and the vehicle’s dynamics model. Numerical simulations and indoor experiments are conducted to validate the feasibility of the proposed approach, with an analysis of the results.

Six different model architectures are used: a finite impulse response multilayer perceptron (MLP-NFIR), a long short-term memory (LSTM) network, a gated recurrent unit (GRU) network, a local model network with regularized finite impulse response models (LMN-NRFIR), a local model network with auto-regressive with exogenous inputs models (LMN-NARX), and a local model state space network (LMSSN).

As a process, a real-world system (Diesel engine) with high system complexity due to multiple feedback paths, strong nonlinearities, and infeasible regions is chosen, which allows a proper investigation of the data-based methods. The sGOATS achieves the best space-filling property, an even excitation of all frequencies, and provides good model qualities.

However, limited application is seen in real-world applications due to challenges in guaranteeing safe system operation, required experiment time, and required a-priori system knowledge and models in existing methods. In this work, we propose a novel exploration method, which addresses simultaneously the challenges associated with safe and time-efficient exploration while dealing with system uncertainty. This method integrates a reciprocal Control Barrier Function and an on-line learned Gaussian Process Regression model. For safe system operation, we leverage the information from the reciprocal Control Barrier Function to limit the step size of the agent’s actions, when approaching the safety boundary. To make this exploration process time-efficient, we use the information gain metrics that are calculated using the estimation of the action-values by an on-line learned Gaussian Process Regression model to determine the direction of the agent’s actions. We demonstrate the potential of our exploration method in simulation and on a vehicle test-bench for efficiency-optimal calibration of a thermal management system for battery electric vehicles. To quantify the benefits in terms of safety, optimality, and time efficiency, we benchmark our exploration method with random and uncertainty-driven exploration methods in a simulation environment. For the studied test case, the proposed exploration method satisfies the safety constraint and it converges to within 1.25% of the true optimal action while requiring 28% and 18% lower experiment time compared to the random and uncertainty-driven exploration methods, respectively. For the proposed method, its performance is also demonstrated on a vehicle test bench.

Sufficient motion in such HWMR systems relies on a multi-stage power transmission mechanism that integrates control valves, hydraulic motors, gearboxes, and, ultimately, nonlinear ground-interaction wheel dynamics on rough terrain. Deviations in each stage of these independently operated wheel systems—arising from modeling uncertainties and disturbances such as wheel slippage and uneven torque distribution on rough terrain—can disrupt motion balance between wheels and further amplify deviations. This can lead the robot to deviate from its course, oscillate, or lose traction, ultimately resulting in overall instability, which may pose a risk to the heavy-weight robot’s surrounding environment. To develop a synchronous control strategy for distributed HWMR systems to mitigate such challenges in uncertain environments, this paper proposes a novel robust torque-observer-based valve control (RTOVC) framework for IWD-actuated wheels, guaranteeing robustness and uniformly exponential stability of the entire system. As a foundation for this approach, a robust torque observer network based on an adaptive barrier Lyapunov function (BLF) is designed to obtain the required wheel/motor torques, ensuring that the actual velocities of IWD-actuated wheels align with the reference values in motion dynamic frames in the presence of wheel slippages. It eliminates the closed-loop dependency on fault-prone torque or pressure sensors in hydraulic actuation mechanisms. Building on this, an additional adaptive BLF-based control network in the valve-actuated hydraulic mechanism is employed to regulate fluid flow, generating the required torque in the first network for each wheel under system uncertainties. The RTOVC framework reduces fault risks in HWMRs by constraining key input–output signals—such as valve control signals, actual wheel velocities, tracking errors, and required motor/wheel torques—within logarithmic BLFs, ensuring safe operation. A comprehensive experimental analysis on a 6,500-kg hydraulic-powered IWD-actuated HWMR operating on rough terrain, where failures may arise due to severe slipping conditions and hydraulic system uncertainties, confirms the RTOVC’s robust performance compared with two other state-of-the-art control strategies.</div></div>","PeriodicalId":50615,"journal":{"name":"Control Engineering Practice","volume":"164 ","pages":"Article 106459"},"PeriodicalIF":5.4,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144522848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The event-triggered mechanism primarily selects more appropriate estimation models based on vehicle states, rather than reducing computation frequency. Meanwhile, the federated structure integrates estimates from each sensor. Secondly, a nonlinear model incorporating the hysteresis effect of the electric-pneumatic composite braking system is developed.
