Selective harmonic mitigation (SHM-PWM) is a low switching frequency modulation technique commonly employed in medium voltage - high power multilevel converters to increase their efficiency. Several different formulations, based on multi-objective cost functions, have been published in the technical literature to implement SHM-PWM together with total harmonic distortion (THD) minimization. However, a comparison is required to determine which formulation is more effective to solve the problem. In this way, this paper provides a novel comparison based on a study of the formulation equations and a brute force analysis. The formulation parameters have been optimized to offer a fair comparison in the brute force analysis. With the aim of considering the effect on the convergence of search algorithm effectiveness, the formulations have also been compared considering the results provided by a hybrid meta-heuristic-numerical search algorithm. As a result, the advantages and disadvantages of every formulation, besides some rules to optimize their parameters, have been extracted.

This paper proposed a novel sag classification method that is a parallel convolutional neural network with multi-task learning (PCNN_MTL). Voltage sag events will not only cause a sharp drop in the amplitude of single-phase or multi-phase voltage but also bring about phase changes after propagation. In order to obtain distinguishing feature information, a one-dimensional convolution neural network is employed to extract the distortion characteristics of single-phase voltage, and a two-dimensional convolution neural network is utilized to capture the correlation characteristics between three-phase voltages. The extracted features of them will be fused in the full-connection layer. Finally, the multi-task learning is adopted to classify the sag signals with two classification modes which are the ACD classification and the A~G classification. The experimental results show that the proposed PCNN_MTL achieves good classification effects in both classification modes, and can realize the refined classification of 19 types of sags.

In the context of the industry 4.0, production lines must be flexible, easily configurable and quickly adaptable to the variation of production. For assembly operations, which are usually done by special machines or human operators, a multirobot cell gives a more flexible solution. Robots trajectories are generated using a CAD model of the cell with an offline programming software. The drawback when using offline programming is the difference between the real trajectories of robots and the theoretical ones. In this paper, a method to calibrate multirobot cell is proposed. This calibration consist in identifying the real positions and orientations of each robot frame with respect to the other. This operation allows to improve the accuracy of the robotic cell by reducing the gap between the CAD model and the physical cell. The calibration is carried out by using a laser profiler and a reference sphere.

Recently, the penetration of new energy sources and power electronics has been increasing. To support the grid, grid-forming control technologies for renewable energy generation have been proposed. Power control is the key technology of grid-forming converters in achieving grid support. However, in these control methods, the dynamic response of the transient power is usually affected by overshoot and oscillation. In order to improve the dynamic response of the injected instantaneous power, a grid-forming control strategy based on synchronous power controller (SPC) is presented in this paper. A new design idea is proposed to simplify the control model of the power loop, which not only enables accurate theoretical modeling of the active power control dynamics but also allows a quick analysis and parameter design. The comparison of theoretical analysis and simulation experiments verifies the effectiveness of the control method in providing auxiliary services that contribute to the angle and frequency stability of the future grid.

High frequency (HF) signal injection is commonly used in sensorless permanent magnet synchronous motor (PMSM) drives at low speeds and standstill. However, the extra acoustic noises caused by additional signal injection impose restrictions on its further applications. To address this issue, a pseudo-random frequency pulse voltage injection scheme is proposed for sensorless PMSM drives at low speeds. Compared with the pseudo-random signal injection, the proposed pseudo-random frequency pulse voltage injection scheme with pulse width adjustment can make all the discrete harmonics in the noise spectrum disappear, thus achieving effective noise attenuation. The signal injection design is performed via current power spectral density (PSD) analysis. According to the form of the injected signals, the signal demodulation procedure is designed to obtain estimated rotor position. The validity of the proposed scheme is verified on 2.2-kW IPMSM platform.

Modular plants build a production system by integrating a set of pre-designed modules. Integration of these modules, supplied by different vendors, is performed using various design tools during the engineering phase. The integration process must perform a rigorous validation of the correctness of a module specification (MTP). Otherwise, the integration process can fail without providing enough failure details. Consequently, Such a failure at the later stage can significantly impact implementation, testing, integration, and SAT. In this paper, we describe a validator tool, that allows a plant designer to define a set of invariants that must be satisfied so that an MTP can be deemed fit for integration. We have tested the validator on a set of MTPs and reported our findings. We expect that the use of such a validator can significantly reduce the possibility of introducing errors during the engineering phase.

Contemporary Cyber-Physical Systems (CPS), such as autonomous vehicles, are driven mainly by data. Combining timing and data semantics in such Data-Driven systems is crucial to assure safety. This paper proposes an extension of SmartData to support online safety monitoring. By following a Data-Driven Design, we promote a specification of property monitors using Signal Temporal Logic (STL) encompassing Safety Models. Timing aspects from STL specification roots from the timed data intrinsic to SmartData. The property monitors are envisioned as an online monitoring method inside a Safety Enforcement Unit (SEU). The SEU periodically assures the satisfiability of timing and semantics. We demonstrate the proposed design through a case study of an autonomous vehicle modeled using SmartData. The case study considers Mobileye’s Responsibility-Sensitive Safety as a ruler for safety vehicle conditions. Finally, the design provides the online verification capabilities inside the SEU by exploring the interpretation of STL specification as property monitors following the RTAMT library.

In this paper, a framework combining base placement, path planning and redundancy resolution for a mobile manipulator performing sequential tasks, such as screwing, drilling or assembling tasks, is proposed. For a set of given tasks, the outputs of the proposed algorithm meet the following practical performance indicators: minimization of the number of the base positions, minimization of the number of manipulator joint configuration changes, feasibility of each task considering the force capacity of the manipulator (which takes benefit of redundancy resolution) and path planning of the end-effector motion with obstacle avoidance. The effectiveness of the proposed approach is evaluated considering a 3 DOFs mobile platform and a 7 DOFs manipulator performing screwing in a application with 42 tasks.

Hybrid electrical systems are complex to size because there is a strong dependence between components design and power management control law. In order to pre-size a hybrid rally race car, which uses hydrogen and batteries as energy sources, an offline power management method, which is formulated in a combinatorial form, is developed to be readily incorporated in a bi-level optimization problem. The exponential growth of memory space as a function of the size of the problem, in particular for long power profiles, is a well-known problem of this type of approach. This paper proposes solving techniques, which consist in using battery state trajectory following and constraints relaxation. Obtained results show satisfying improvements compared to the state of art. Sensitivity analyses show the influence of resolution parameters on the optimization problem solution and its required computation resources.
