The advanced microarchitecture design philosophy prioritizes performance, efficient power management, and thermal output control, with a focus on hybrid computing cores and integrated IP blocks like memory, high-speed I/Os, Cache-Coherent-Fabric, Image Processing Unit, etc. Each IP has multiple Digital Thermal Sensor (DTS) diodes to monitor temperature. These IPs and their diodes are placed micrometers apart inside an SoC. According to the Inverse Temperature Dependency (ITD) effect, transistors slow down as temperature decreases for supply voltages below a critical limit, requiring increased voltage. ITD is an algorithm that involves voltage compensation based on temperature and the minimum voltage (Vmin) needed to switch on a transistor. As the SoC runs colder, more voltage is needed, increasing power consumption, and causing the SoC to hit its power limits (PL1/PL2) at lower temperatures, resulting in performance loss. The proposed solution could improve performance per watt by 5% to 10%, especially at lower temperatures and when exiting a low-power state. The core with the highest DTS temperature will wake up first, preventing hot cores from hitting PL1/PL2 early.

Improving the efficacy of warheads is notably impacted by guidance laws governing impact angle control. In this article, a comparative analysis of the efficacy of different impact angle control methodologies in three-dimensional missile-target interception scenarios is presented. For the comparative study, different kinds of guidance laws are taken into account, including those based on the biased proportional navigation, optimal control, Lyapunov stability method, sliding mode control, and analytical solution based method. The efficacy of the guidance strategy is evaluated by considering the following factors: the continuity of the lateral acceleration profile, the maximal acceleration value, the total control effort, and the ability to respect the field of view constraint.

The use of quadcopters has grown exponentially in countless fields. With the ever-growing demand for automation in today's world, algorithms for the autonomous control of drones have become a major area of research. In this paper, we implement two control strategies, namely Sliding Mode control (SMC) and Super Twisting Sliding Mode control (STSMC), on a 6 Degree of Freedom quadcopter model and compare their performance. Using Fast Fourier Transforms, the two controllers are analysed to enable an effective comparison of the chattering in the control input by defining a suitable index. With this index, we observe a decrease of two orders of magnitude in the chattering present in the input given by the STSMC controller.

In this article, a fully distributed consensus control strategy centered on adaptive active disturbance rejection control (ADRC) with fuzzy logic for adaptiveness is proposed to address the consensus control problem of a multiagent system (MAS) employing wheeled mobile robots (WMR) as agents. The initial step involves transforming the nonlinear and underactuated model of the WMR into a linear one taking into consideration of model uncertainties and external disturbances. Then, an adaptive extended state observer (ESO) based on ADRC framework is designed to estimate the total disturbance. Finally, an adaptive control protocol with disturbance compensation based on the transformed model is presented to achieve consensus for both fixed and switching communication topology. Simulation results verify the effectiveness of the consensus control algorithm.

SynRM field-oriented control is analyzed. SynRM is a viable option for variable-speed applications such as electric transportation. For optimum performance in a complete speed range, efficient control is necessary. SynRM has nonlinear characteristics;hence, the control needs to be dynamic with the change in operating point. Using finite element (FE) analysis, the machine's non-linearities can be considered, and therefore, more efficient control can be developed. It helps find the stable operating range above base speed where the field is highly weak-ened and deteriorated. The paper discusses different operating regions and the implementation of a control algorithm using lookup tables in an FE-based co-simulation platform.
