Assuring the cyber security of these systems is a continual challenge and an active area of research; in the case where an aircraft has been compromised by a malicious actor, digital forensics can be utilized to investigate what and how the incident occurred. This research answers a simple, yet fundamental question on the security of aircraft: whether useful digital forensic artifacts be obtained from embedded real-time systems on aircraft. The highly reliable file system (HRFS) utilized by VxWorks was analyzed and described to align with the generalized descriptions of file system formats accepted in academia. The Sleuth Kit (TSK), an open-source forensic toolkit, was analyzed and extended to include functionality to support this file system, and a proof-of-concept implementation to obtain digital forensic artifacts from real-time operating systems on aircraft was developed. This research finds that the proposed implementation can perform file analysis and recovery from a VxWorks generated HRFS-formatted file system and can be generalized to show that embedded real-time systems can provide useful digital forensic artifacts.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"46 4","pages":"278-287"},"PeriodicalIF":0.0,"publicationDate":"2023-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71903515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a proven fact that active harmonic filters (AHFs) are costly solutions though have proved better than passive harmonic filters. Except sizing and resonance problems, tuned passive harmonic filters (TPHFs) are proved to give economical solutions with little compromise on their performance. The accurate design of TPHFs gives a greater impact on its performance. The triple-TPHF (TTPHF) is essential to alleviate first three dominant ac side current harmonics simultaneously at the high voltage direct current (HVdc) converters and it is proved better than the single and double TPHFs. Existing equivalent methods of TTPHF design failed to give satisfactory performance under dynamic conditions. Hence, this article introduces a novel parametric method-based design of TTPHF, which will give better performance under static and dynamic loading conditions. The results also reveal that the proposed TTPHF design method will perform better than the existing methods.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"46 4","pages":"270-277"},"PeriodicalIF":0.0,"publicationDate":"2023-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71903514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The complex dynamical behavior of the proposed system is studied in detail by analyzing its equilibria, Lyapunov spectra, and bifurcation diagram. The feasibility and accuracy of the novel attractor are examined by constructing its analog circuit implementation. Additionally, periodic states of the system are examined in both numerical and PSpice simulations, as well as an analog circuit implementation. The hardware experimental results are highly compatible with numerical and PSpice simulations. As can be seen from the numerical simulations and hardware implementation, the presented system shows sensitive and rich dynamic behaviors in a small range of system parameters. The proposed oscillator circuit is also cost-effective, as it has only seven terms. Additionally, a sliding mode controller (SMC) is presented to control the novel attractor. The stability of the designed SMC is proven via the Lyapunov stability method. Lastly, a microcontroller-based implementation is realized, and it is seen that the experimental results are in good accordance with the simulation results. The correctness of the proposed controller is approved by theoretical analysis, numerical simulations, and experimental results.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"46 3","pages":"228-236"},"PeriodicalIF":0.0,"publicationDate":"2023-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68026229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis of the switching sequence for the operation of 15 level multi-level inverter (MLI) topology using logical gates is introduced in this article. A 15-level reduced switch topology is proposed which consists of eight switches. The main focus is to analyze the procedure of generating a pulse pattern for the eight switches in the circuit and to obtain the logical expression. Key Findings: The input pulse for the generation of eight different pulse patterns is obtained by MC-PWM technique. Several MC-PWM techniques, including phase disposition (PD), alternate phase opposition disposition (APOD), and phase opposition disposition (POD), are available. POD were applied to the proposed reduced switch topology using the same logical expression and the results were analyzed. MATLAB/Simulink is employed in the execution of the simulation work. The desired pulse pattern is simulated in real time and generated with the assistance of dSPACE 1104. Various modulation index (MI) and several PWM algorithms are used to examine the total harmonic distortion (THD) comparison study.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"46 3","pages":"237-245"},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68026232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the equivalent resistance of the on-board battery charger continuously fluctuates during operation, a battery charging algorithm based on an improvised continuous current (CC)–constant voltage (CV) is proposed. This article introduces the design of an integrated stationary IPT system to inductively transfer power from a transmitter pad positioned on the ground and the receiver pad embedded under the chassis of an EV. An innovative feature of the design is the implementation of a magnetic switch sensor that is incorporated into both the transmitting and receiving wireless charging circuitry to ensure optimum alignment for IPT. The power electronics design focuses on the implementation of an H-bridge converter incorporating series–series (SS) compensation topology to use an innovative control algorithm to prioritize battery charging operations. The system is validated through a simulation model in PSIM and a hardware-in-the-loop (HIL) simulation in Typhoon before hardware implementation and testing of the developed prototype. At a test resonant frequency of 23.74 kHz and a nominal air gap separation of 120 mm, the developed IPT system had an overall efficiency of 93.41%.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"46 3","pages":"207-217"},"PeriodicalIF":0.0,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68026230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
