It has become evident that pneumatic muscle-based robots are the most compliant of all soft and semi-soft robotic testbeds under investigation, despite the fact that the artificial muscle-based robot is the most challenging due to its hyperelastic behavior resulting from the constitutive elastic material. The purpose of this paper is to examine the development of a physical pneumatic actuation testbed and the application of control strategies for precision small scale soft robotics control. Moreover, an adaptive PI-Fuzzy like control is proposed for reference signal tracking. It is imperative to note that in this application, the controller's performance is determined by its ability to track a reference signal as well as its ability to minimize the absolute tracking error. The Fuzzy Logic controller (FLC) controller, including the nature of the membership functions and the rule base, is described in detail. Simulations and hardware testing have revealed that the adaptive PI-Fuzzy like controller outperforms the traditional FLC controller in terms of experimental results. Additionally, the actuation speed is controlled under different loading conditions. It is considered that the proposed testbed is capable of controlling and managing multi-configurations of medium to small scale soft-based robots efficiently and effectively.

This paper introduces a novel control strategy, Fixed-time Virtual Inertia (Fxt-VI), designed to enhance frequency stability in islanded microgrids (MGs) that typically lack synchronous generation. Unlike traditional power systems, which rely on physical inertia, MGs necessitate inertia emulation due to the integration of fluctuating renewable energy sources. A key feature of the proposed Fxt-VI control strategy is its ability to quickly resolve frequency deviations within a predefined time frame, regardless of the initial system conditions. This ensures accelerated and predictable stabilization times. A thorough analysis using Lyapunov-based method is developed to validate the stability of the designed control strategy within a fixed time. Simulations in an islanded microgrid setup, including various energy sources such as thermal, wind, solar power plants, and energy storage systems, demonstrate the efficacy of the proposed Fxt-VI controller. Moreover, this paper provides a comparative evaluation of the proposed FxT-VI controller in relation to robust $\mathrm{H}-\infty$ and optimal PI controllers. The results show that it not only achieves quicker stabilization but also maintains lower frequency deviations compared to traditional methods, as assessed through specific performance metrics.

In this paper, given a linear time-invariant strongly connected network, we study the problem of determining the minimum number of state variables that need to be simultaneously actuated and measured to ensure structural controllability and observability, respectively. This problem is fundamental in the design of multi-agent systems, where there are economic constraints in the decision of which agents to equip with a more costly on-board system that will allow the agent to have both actuation and sensing capabilities. Despite the combinatorial nature of this problem, we present a solution that couples the design of both structural controllability and structural observability counterparts to address it with polynomial-time complexity.

This paper presents a smart home automation system based on Raspberry board. Indeed, smart devices are used in order to accelerate control and monitoring operations. The IoT system that was created comprises sensors that produce temperature and humidity information. This data is processed through a Raspberry microcontroller and then transmitted in real-time via Zigbee protocol to the Android mobile app. To measure temperature and humidity, a DHT11 sensor is utilized. To monitor gas leaks in the kitchen, an MQ2 sensor is incorporated. Lastly, a HC-SR04 Ultrasonic sensor is utilized to manage the garage door’s opening and closing. One main feature of the developed home automation system lies in its incorporation of essential components, including real-time functionality, cost-effectiveness, versatility, upgrade potential, and reconfigurable capabilities. Another advantage is the use of the Raspberry card, which is more efficient, higher-performing, faster, and provides better real-time execution compared to other cards.

The approximation of complex dynamical systems models by reduced order models has been considered an important research problem for over four decades, not only in the field of control, but also in economics, image processing, circuit analysis, statistical mechanics, aircraft structures, and more recently in hybrid energy systems, to name just a sampling of fields. In this paper, we provide an overview of the development of balanced truncation and interpolation approaches for reducing linear and non-linear dynamical systems models for the purpose of control analysis and design.

Hardware-in-the-loop simulation (HILS) allows a more realistic evaluation of control approaches than what is possible with pure software simulations, but without the actual complexity of the complete system. This is important for some complex systems such as orbital robots, where testing of the system is typically not possible after its launch, and an on-ground replica is used to validate the performance of such a system. In this article, an impedance-matching approach is presented to match the end-effector dynamics of a fixed-base robot manipulator with that of a target vehicle-manipulator system (VMS), while taking into account the redundant nullspace dynamics in a connected real-time simulation framework. This approach ensures that the forces and torques exerted by the system on the environment matches with that of the simulated system. The contact wrenches used in our approach are not obtained from numerical simulations, but rather from real physical interaction, which is one of the main advantages of our approach. The effectiveness of our method is validated by demonstrating various physical interaction tasks with the environment, using a suspended aerial manipulator as the target system.

This paper considers distributed online nonconvex optimization with time-varying inequality constraints over a network of agents. For a time-varying graph, we propose a distributed online primal–dual algorithm with compressed communication to efficiently utilize communication resources. We show that the proposed algorithm establishes an O(T max{1−θ1,θ1}) network regret bound and an O(T 1−θ1/2) network cumulative constraint violation bound, where T is the number of iterations and θ1 ∈ (0, 1) is a user-defined trade-off parameter. When Slater’s condition holds (i.e, there is a point that strictly satisfies the inequality constraints at all iterations), the network cumulative constraint violation bound is reduced to O(T 1−θ1). These bounds are comparable to the state-of-the-art results established by existing distributed online algorithms with perfect communication for distributed online convex optimization with (time-varying) inequality constraints. Finally, a simulation example is presented to validate the theoretical results. Copyright © 2025, The Authors. All rights reserved.

This project aims to design an IoT home automation application. The suggested system involves a range of sensors gathering temperature and humidity information, then using an Arduino microcontroller linked to an Android mobile app for processing. This enables the transmission of data to the mobile app via Bluetooth, ensuring instant updates. In this context, the temperature and the humidity are measured using a DHT11 sensor. In addition, a MQ2 sensor is employed to manage the detection of gas leaks within the kitchen. Last but not least, we utilize an HC-SR04 Ultrasonic sensor to oversee the operation of the garage door, regulating its opening and closing. The developed home automation system stands out due to its integration of key elements such as real-time operation, affordability, adaptability, upgrade potential, and reconfigurable features.

For medium and high-power renewable energy applications, parallel four-leg inverters are highly recommended to increase the power capability, power rating, and the efficiency of the system. However, a zero-sequence circulating current (ZSCC) will be generated by the difference between the zero sequence voltages (ZSVs) due to unequal output currents and filter inductors, as well as other factors such as different switching frequencies and dead times when the inverters are connected in parallel via common DC and AC buses. The ZSCC will seriously distort the output currents and degrade the control performance and the dynamic response of the overall parallel system. This paper suggests a modified carrier-based SPWM to suppress the ZSCC by eliminating the difference between ZSVs through the adjustment of modulation voltages of the modified carrier-based SPWM. The proposed ZSCC suppression method can successfully achieve the ZSCC suppression even when the parallel four-leg inverters system has unbalanced output current sharing and filter inductances. The simulation results based on the parallel four-leg inverters distinctly confirm the effectiveness of the suggested ZSCC suppression method.
