“…Some of the works of PI λ D µ controllers are reported in [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Similarly, the works on a DC motor can be seen in [19][20][21][22][23][24][25][26][27][28][29]. Recent works of analog PI λ D µ controller on a DC motor includes implementation by Operational Transconductance Amplifiers (OTA) [30] or using CMOS op-amp [31].…”

In this paper, the performance of an analog PI λ D μ controller is done for speed regulation of a DC motor. The circuits for the fractional integrator and differentiator of PI λ D μ controller are designed by optimal pole-zero interlacing algorithm. The performance of the controller is compared with another PI λ D μ controller—in which the fractional integrator circuit employs a solid-state fractional capacitor. It can be verified from the results that using PI λ D μ controllers, the speed response of the DC motor has improved with reduction in settling time ( T s ), steady state error (SS error) and % overshoot (% M p ).

“…The realisation of single element fractional capacitor with varying α (fractional exponent) is an important requirement as it provides additional degree of freedom in electronic circuit design [1]. The fractional capacitor with tunable α has found its utility in oscillator circuits [1][2][3], in fractional-order controllers [4][5][6][7][8], in fractional phase-locked loop and filter circuits [9][10][11][12]. A single component fractional capacitor makes the above circuits compact and easy to handle.…”

This study presents the optimisation of the various parameters (wt% of multiwalled carbon nanotube, pore size, size of the middle plate and time of testing) for evaluation of fractional exponent of a solid-state fractional capacitor. For this, full factorial design of experiments is carried out to understand the crucial parameters, which have an effect on fractional exponent α. Then, contributions of each of the significant parameters are estimated. Later, by one-way analysis of variance, the combination of various parameters by which one can obtain fractional capacitors of varying α is given in detail. The fractional capacitor for which the optimised design is done has a constant phase angle in between 0° and −90° in the frequency range from 1 to 100 kHz.

“…The special forms of controllers such as [8,9,[13][14][15], [16,17] controllers are used most of the time due to their design simplicities, though there are some derived alternatives ( ) [18], ( ) [18], + [19], and fractional lead-lag compensator (FLLC, [20]).…”

Some all-purpose design equations are derived for designing fractional order controllers for integer order plants with time delay. The results combine many design techniques appearing in the literature. In addition to plotting the global stability boundaries, they can be used to achieve desired gain and phase margins with a flat phase response near the gain cross over frequency. So, robustness can also be guaranteed. Further, satisfactory output disturbance and high frequency noise rejections can be realizable. An example is treated to make connections with the already existing results in the literature, which proves the usability of the obtained design equations.
