“…Consequently, stability analysis must be included in the searching process as a penalty condition. The eigenvalue theorem [1], [2], [6], [12], [15], [16], [18] based on small-signal stability analysis is applied with the dynamic model for stability analysis in the present study. The ATS algorithm uses its stability analysis mechanism to search the MEA EPS controller parameters until it reaches the acceptable condition.…”

An important reflection of the overall efficiency, reliability, and passenger safety of a more electric aircraft (MEA) is the output performance of its electrical power system (EPS) controller. This output performance encompasses the rise time, setting time, and percent undershoot of the voltage across the capacitor bank. Therefore, this article presents an optimal controller design using an artificial intelligence method called the adaptive tabu search (ATS) algorithm. The state-variables-averaging model is applied with the ATS algorithm to reduce computational time. Moreover, stability analysis based on the eigenvalue theorem is used as the penalty condition during the searching process to avoid unstable operation. The output performance of the proposed controller design is superior to that of the conventional controller design. All design results are verified by good agreement with MATLAB and hardware-in-theloop (HIL) simulations.INDEX TERMS More electric aircraft, vector control, state-variables-averaging model, adaptive tabu search algorithm. I. INTRODUCTIONAccording to published concepts for more electric aircraft [6]. aircraft performance optimization, flight reliability improvement, and passenger safety improvement are essential tasks. Altering the MEA controller design is an approach with strong potential to accomplish these tasks. Artificial intelligence (AI) techniques are required to achieve the optimal output performance of the MEA's electrical power system (EPS) controller in terms of the rise time, setting time, and percent undershoot of the voltage across the capacitor bank. AI can be used for controller design and many other functions. For example, AI has been applied to the design of active power filters for the adaptive tabu search (ATS) algorithm [7] and genetic algorithm [8], power flow optimization based on particle swarm optimization [9], ant colony search algorithm [10], antenna array design using artificial bee colony algorithm [11], and the application of the ATS algorithm to instability mitigation [12]. However, one of the crucial problems that arises when applying AI techniques to the EPS of MEA is the simulation time. This is because the simulation of EPS using software packages such as PSIM and MATLAB causes huge computational time due to switching behavior. Thus, a time-invariant model is necessary and sufficient for the controller design. There are several reasonable methods for deriving the timeinvariant model of EPS. The generalized state-space averaging modeling technique [13], [14] has been universally used for single-phase rectifiers of AC distribution systems and the power converters of DC distribution systems. The direct quadrature (DQ) approach [1], [2], [6], [12], [15], [16] is suitable for power converters in three-phase AC distribution systems. The nonlinear average-value method modeling technique [17] has been applied to analyze 6-and 12-pluse diode rectifiers.Based on a literature review, the AI technique called the ATS algorithm is selected for use in the present stud...

Multi-converter system is mainly used in advanced automotive systems. Different converters and inverters are taking part in automotive systems to provide different voltage levels in a multi-converter system. It involves constant voltage load (CVL), constant power load (CPL) and other loads. The CPL in such systems offers negative impedance characteristic and it creates a destabilizing effect on the main converter. The effect of destabilization can be reduced by increasing the CVL or inserting parasitic components. Attempts have been made by authors to improve the stability by using parasitics of different components such as switch, diode and inductor. Influence of insertion of parasitics including the series equivalent resistance of the filter capacitor and variation in CVL on the performance of main converter is mathematically analyzed and conflicting behavior between system stability and efficiency is observed. The optimum solution between these two functions is obtained by using multi-objective decision making (MODM) by varying parasitics of different components and CVL. An attempt has been made to demonstrate the effect of CVL load and the parasitics on the stability and efficiency of the main converter, experimentally.

Weighted Bandwidth Method for Stability Assessment of Complex DC Power Systems on Ships

et al. 2021

In shipboard DC grids, tightly controlled load converters can impair the system stability, thus provoking the ship blackout. Conversely, load converters regulated by low control bandwidths are capable of inducing a stabilizing action. This compensation is verifiable if the loads are few. On the contrary, the balancing of control dynamics is hardly evaluated if the bus feeds multiple (i.e., hundreds or more) DC controlled loads. In this paper, the weighted bandwidth method (WBM) is presented to assess the small-signal stability of a complex shipboard power system by aggregating the multiple converters into two sets of controlled loads. Once the validity of the aggregation is proven, a stability study is performed on the two-loads system. As the last system is more inclined to instability than the initial multiple-loads system, the verification of the two-loads stability criterion guarantees that the shipboard DC grid also remains stable. Finally, emulations on HIL verify the proposed stability assessment thus providing the first unique verification of WBM.
