A hyperbolic hybrid partial differential equation (HHPDE) continuum model is constructed to describe the dynamics of RMSs suffering from unexpected workstation faults, by considering that machinery failures of workstations lead to discarding of defective products. In the case that the faults are known, a fault-tolerant impulsive observer is designed for state estimation of the RMSs. In the case that the fault information is uncertain, a diagnostic observer based residual evaluation logic is developed for fault detection first. Upon detecting the faults, an adaptive impulsive observer is then proposed to simultaneously estimate both the system states and the faults. In addition, by using a piecewise Lyapunov function candidate, sufficient stability conditions that guarantee the exponential input-to-state stability (EISS) of the estimation error are formulated in terms of linear matrix inequalities (LMIs). Finally, the feasibility and effectiveness of the proposed strategy are validated through numerical simulations.","PeriodicalId":13039,"journal":{"name":"IEEE Transactions on Circuits and Systems I: Regular Papers","volume":"72 4","pages":"1773-1786"},"PeriodicalIF":5.2,"publicationDate":"2025-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143726355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transformer-based IR methods have significantly improved the visual effects of the restored images. However, deploying complex IR models on edge devices is challenging due to massive parameters and intensive computations. Moreover, existing accelerators are typically customized for a single task, resulting in severe resource underutilization when executing multiple tasks. Therefore, this paper develops an algorithm-hardware co-design framework to accelerate a novel CNN-Transformer cooperative model for multiple IR tasks. Firstly, on the algorithm level, an Efficient Restoration Foundational Model (ERFM) is proposed to recover corrupted images from various degradations with low model complexity. Secondly, to guide adaptive corruption removal, a novel prompt learning scheme is introduced to fuse context-related degradation cues and boost high-quality reconstruction. Thirdly, on the hardware level, an integer approximation method is proposed to avoid expensive hardware overhead caused by complex nonlinear operations, such as layer normalization and softmax while maintaining comparable IR quality. Moreover, a head stationary dataflow and softmax fusion mechanism are designed to reduce data movement and enhance on-chip resource utilization. Finally, an overall hardware architecture is developed and implemented in TSMC 28 nm CMOS technology. Experimental results show that our ERFM achieves better visual perception than other baselines on seven challenging IR tasks without task-specific fine-tuning.

Then, a novel controller updating mechanism is developed by discontinuously comparing the optimal value functions of the modified optimization problem and the original optimization problem, which saves the communicational and computational resources. Specifically, the control performance is optimized over all possible uncertainties and deception attack realizations using a min-max optimization technique, while the DoS attacks can be tackled with the parameterization feature of the control input sequence.

However, spuriously generated Background Activity (BA) noise events can significantly degrade the quality of DVS output and cause unnecessary computations throughout the image processing chain, reducing its energy efficiency. Near-sensor filters can mitigate this problem by preventing the BA noise events from reaching downstream stages. In this paper, we propose a novel, hardware-efficient, spatio-temporal correlation filter (HAST) for near-sensor BA noise filtering. It uses compact two-dimensional binary arrays along with simple, arithmetic-free hash-based functions for storage and retrieval operations. This approach eliminates the need to use timestamps for determining the chronological order of events. HAST uses much lower memory and energy compared to other hardware-friendly filters (BAF/STCF) while matching their performance in simulations with standard datasets; for a sensor of resolution <inline-formula> <tex-math>$346times 260$ </tex-math></inline-formula> pixels, it requires only 5–18% of their memory, and about 15% of their energy per event for correlation time <inline-formula> <tex-math>$tau $ </tex-math></inline-formula> ranging from 1 to 50 ms. The memory and energy gains of the filter increase with sensor resolution. In FPGA implementation, HAST achieves about 29% higher throughput than BAF/STCF while utilizing only about 5% of their memory. The filter parameter values can be chosen by Design Space Exploration (DSE) for optimized performance-resource trade-offs based on application requirements.","PeriodicalId":13039,"journal":{"name":"IEEE Transactions on Circuits and Systems I: Regular Papers","volume":"72 3","pages":"1332-1345"},"PeriodicalIF":5.2,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143496445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reduce the communication burden, the dynamic event-triggered mechanisms (DETMs) are introduced along with the switching mechanism for multiple topologies. Specifically, the topology switching process is further viewed as a general uncertain semi-Markov (GUSM) jumping process. This jumping process along with the DETM is thus represented by hidden Markov model (HMM). Then the distributed integral-type sliding mode controller is constructed on the top of the HMM. Sufficient conditions for the desired performance of the closed-loop synchronization error system are derived by constructing the mode-dependent Lyapunov-Krasovskii functional (LKF) with extended dissipativity analysis.
