“…Figure 13 shows the proposed structure of the proposed WTE that is implanted at our laboratory [32]. The controlled DC motor provides a variable output torque, which we consider equal to an adapted aerodynamic torque via an ideal gearbox [48]. Equation (23) indicates the proportionality between the armature current and the DC motor torque [49]:…”

“…and its proper use and application depends mostly upon the control methodology being used for the converter to get the desired response. The principle aim is to consistently give steady output response across the converter in spite of lot of disturbances and variations in the system being added from external known and unknown sources to maintain good and unaffected result [3,4,12,18,24]. In any case, the control techniques for these converters are not robust for the case model vulnerabilities just as the outer disturbances.…”

This paper is discussed towards the issue of variations happening in the voltage control method of DC-DC boost converter. Quantitative feedback theory (QFT) is adjusted to efficiently plan a robust PID regulator, which is acknowledged utilizing only output voltage of the plant sensed by voltage sensor. The benefits of the explained PID configuration by utilizing the QFT design (Tarakanath Kobaku et al. 25) is proved with the fact that it disposes the problem of extra work and ad-hoc tuning of PID gain utilizing the regular PID methods, current measurement isn't needed, it provides the design for case of nonminimum phase of boost converter even if there is restrictions on the bandwidth and disturbance factors are already included in the design of QFT based controller with the help of QFT bounds and thus disturbance effect is considered in the output of system. Various simulation results are taken in each case i.e. conventional PID controller and sliding mode controller. Here results are compared with the QFT based controller to verify the importance of this controller over other two controllers in terms of output response, reference tracking, line regulation and most importantly on the basis of cost effectiveness.

This article proposes a novel method, inspired from eigen decomposition technique, to design a quantitative feedback theory (QFT) based robust controller for a multiple input multiple output (MIMO) uncertain plant. The proposed method is a direct and sufficiently generalized one. Unlike existing practice, it does not require to transform a “n×n” MIMO‐QFT based design problem into “n” sequential multiple input single output QFT based design problems. Apart from the frequency dependency, the frequency response of a MIMO system also has the spatial dependency. This makes the frequency domain analysis and design for a MIMO system, more challenging than its SISO counterpart. Three new concepts namely directional transfer ratio (DTR), output directionality (OD), and principle of control along characteristic vectors (PCCV) are introduced to take care of the complexities of the frequency response of a MIMO feedback system. The DTR, OD, PCCV and existing techniques of QFT are combined together to develop the proposed design method. A case study is presented considering a “2×2” ill‐conditioned plant to illustrate the method. The proposed method is expected to open up new avenues in the area of MIMO‐QFT based design.
