To address this issue, this paper proposes an adaptive continuous twisting (ACT) control method to further improve the control accuracy and anti-interference ability of the PMSM system. Firstly, a continuous twisting controller is designed to generate a continuous signal, which is utilised in the speed loop. It can guarantee that the tracking error of the speed regulation system finite-time converges to zero. This not only enhances the robustness of PMSM system, but also effectively weakens the control chattering. Secondly, on this basis, an ACT controller is constructed to handle the disturbances with unknown bounds in PMSM systems. Finally, simulation and experimental results show that the proposed control method can improve the performances of PMSM system.KEYWORDS: PMSMadaptive controlspeed controlcontinuous twisting controlDisclaimerAs a service to authors and researchers we are providing this version of an accepted manuscript (AM).

The use of cardiac pacemakers was estimated to be around 1.14 million in the year 2016 and is expected to increase to 1.43 million by the year 2023. Based on the frequency of usage the lifetime of a pacemaker can last between 6 to 10 years. To prolong the lifetime of the pacemaker, a low power filter design is presented. The pulse that comes out of the pacemaker has exponential noise and myo-potential noise. The Least mean square (LMS) filter with Co-ordinate Rotation Digital Computer(CORDIC) filters the exponential noise signal and retrieves the desired pace pulse. The CORDIC architecture used here is realised using FSM computational technique, because FSM offers a simple hardware circuitry. Digital circuits highly rely on clock signal to track the time and execution of functions that are programmed. This irreplaceable signal requires a control module that would make it more efficient and audacious. This is the prime reason for the evolution of clock gating technique. Similarly the leakage power caused by the power source also requires attention. With the boom of deep submicron technologies leakage power has started to occupy 30-50% of the total power consumption. Power gating technique helps to resolve this issue significantly. In this proposed method, Integrated coarse grained Power and Clock gating technique is employed to reduce the power dissipation of the LMS filter. A comparative study of Latch, AND and OR based clock gating with Forced transistor stacking and sleep transistor whose width and length is doubled from the rest of the Complementary metal oxide semiconductors is also performed. The design is implemented using 250 nm CMOS technology. The implementation of clock gating technique has resulted in a 41.35% average reduction in dynamic clock power dissipation. The power gating technique has resulted in 26.08% reduction in static input power dissipation. The total power savings on integration of clock and power gating techniques is found to be 36.95% from the non-gated CORDIC LMS filter design.KEYWORDS: Clock gatingpower gatingpacemakerCORDIC algorithmLMS filterDisclaimerAs a service to authors and researchers we are providing this version of an accepted manuscript (AM).

Also, the proposed TITO converter topology uses only three switches when compared to conventional multiport converter where the number of semiconductor switches are higher. The conventional converter has a higher number of components whereas the proposed converter has a reduced number of conduction components as well as switching semiconductors.

A detailed steady-state analysis is also given, providing its operating modes, equilibrium values, and design guidelines. The modelling process consists of two stages. First, the nonlinear model is obtained using the state-space averaging technique. Subsequently, the averaged model is linearised by applying the small-ripple approximation and the small-signal model is achieved. Furthermore, the developed small-signal model is employed to derive three significant transfer functions of the converter. The proposed converter model is valid for the continuous conduction mode (CCM) when the duty cycle is lower than 0.5. To be used in validation studies, an exemplary converter with 144W rated power that steps down 320V input voltage to 24V is designed. The accuracy of theoretical analyses is confirmed by the simulation results of the designed converter. Similarly, all proposed models are validated with the simulations done in both frequency-domain and time-domain. The results show that the proposed parametric model response closely matches that of the switching (non-parametric) model and hence it can be safely used for controller design in feedback systems.KEYWORDS: Cascade buck converterhigh step-down conversion ratiosteady-state analysisstate-space averaging techniquesmall-signal modeltransfer functionDisclaimerAs a service to authors and researchers we are providing this version of an accepted manuscript (AM).

Compared with traditional PT controlled Buck converters requiring two pulse train generators, only one single memristive pulse generator with controllable duty cycle is used to regulate the output voltage. To suppress the low-frequency oscillations of the PT-controlled Buck converter in continuous conduction mode (CCM), an inductor current based PT (IC-PT) control method is devised with the proposed MR-based pulse generator.

However, it faces implementation challenges in densely populated networks due to its computational complexity. In NOMA, for decoding Nth user information at the receiver end, it needs to perform (N−1) times perfect Successive Interference Cancellation (SIC) operation. Hence, in a dense network, where the number of users is high, the implementation of NOMA becomes tedious. In order to improve the performance of NOMA implementation, in this work, the concept of Cooperative Modulated-NOMA (CM-NOMA) is applied in the considered densely populated networks model. Performance analysis of the system in terms of outage probability, Symbol-to-Error Rate (SER) and achievable data rate in both one-to-one and cooperative communications scenarios are done. The analytical expressions are also validated using Monte Carlo simulation. The results show that the deployment of CM-NOMA in a densely populated network increases the performance of the system, and also reduces the computational complexity.KEYWORDS: 5GNon orthogonal multiple access technique (NOMA)Cooperative modulated-NOMA (CM-NOMA)Outage probabilitySuccessive interference cancellation (SIC)DisclaimerAs a service to authors and researchers we are providing this version of an accepted manuscript (AM).
