“…The proposed work presents the design of Cuk converter for the application on the low-voltage side DC supply EVs. The modelling and small signal analysis of converters in continuous conduction mode (CCM) with various conventional control strategies such as linear control, Z-N tuned proportional-integral (PI), linear quadratic regulator (LQR) tuned controllers, circuit averaging method and so on were used to regulate the output voltage of the converter but the response attained is not satisfactory under various operating point, sensitivity to parameter variations, instability due to line and load variations [2][3][4][5][6]. To overcome such drawbacks, robust non-linear control methods such as voltage control, current control and sliding mode controller (SMC) methods were used to improve the performance of the converter.…”

In this Letter, a hybrid particle swarm optimisation and gravitational search algorithm (PSO-GSA) to tune the parameters of proportional-integral (PI) controller operating in cascade with sliding mode controller (SMC) is proposed for the design of Cuk converter for low-voltage electric vehicle application. The PI controller in the outer loop regulates the voltage and SMC in the inner loop regulates the current of converter operating in continuous conduction mode. The main objective of Cuk converter with PSO-GSA tuned PI & SMC controller is to track the reference voltage amidst disturbances, and to reduce the performance indices such as integral absolute error (IAE) and integral time absolute error. Initially, PI controller was tuned using Routh Hurwitz and root locus method. Then to improve its steady-state performance index, PSO-GSA technique is applied to tune the proportional and integral gains. To validate the effectiveness of the proposed scheme, the performance indices such as IAE, integral squared error was measured and compared. The results obtained reveal that IAE is reduced to minimal value and the solution converges at a faster rate with the proposed controller than the conventional control methods. Moreover, the stability analysis was carried out using the Lyapunov method of stability.

“…Thus, the error between the reference current I* ref and the phase current I is used by the current control to compute a variable duty ratio such that the phase current emulates the reference value. It should be noted that Integral Proportional (IP) controller is adopted for the speed loop considering both overshoot and disturbances rejection [20] and Proportional Integral (PI) controller is introduced in the current loop to guarantee the dynamic response.…”

A New Control Method for Vibration and Noise Suppression in Switched Reluctance Machines

Due to their inherent advantages such as low cost, robustness and wide speed range, switched reluctance machines (SRMs) have attracted great attention in electrical vehicles. However, the vibration and noise problems of SRMs limit their application in the automotive industry because of the negative impact on driver and passengers’ comfort. In this paper, a new control method is proposed to improve the vibratory and acoustic behavior of SRMs. Two additional control blocks —direct force control (DFC) and reference current adapter (RCA)—are introduced to the conventional control method (average torque control (ATC)) of SRM. DFC is adopted to control the radial force in the teeth of the stator, since the dynamic of the radial force has a large impact on the vibratory performance. RCA is proposed to handle the trade-off between the DFC and ATC. It produces an auto-tuning current reference to update the reference current automatically depending on the control requirement. The effectiveness of the proposed control strategy is verified by experimental results under both steady and transient condition. The results show that the proposed method improves the acoustic performance of the SRM and maintains the dynamic response of it, which proves the potential of the proposed control strategy.

Closed loop control strategy is indispensable in power converters to meet the desired load requirements. PI controller is one among the existing control schemes. This scheme has a single loop arrangement with proportional and integral gains in the forward path. A double loop control strategy having proportional gain in the feedback path and integral gain in the forward path called the Integral Proportional -IP controller is proposed in this paper for Buck converter control. The use of IP controller enhances system dynamic response and reduces undesirable peak overshoot compared to conventional PI controllers. IP controller also reduces system's sensitivity to controller gains. Responses of both controllers are analyzed by performing output voltage regulation of Buck Converter with the help of PSIM software.Simulation results show that the IP controller has better response than PI. Such a control arrangement is essential in applications, where a smooth power output is inevitable.
