“…Delay dependent stability analysis which contains the data on the size of the delay is the principal kind and the delay-independent stability analysis is the second kind. 9,10 The independent stabilization of delay offers a controller which can quiet down the system regardless of the delay size. 11 On the other hand the delay dependent stabilizing controller is troubled with the delay size and for the most part gives the upper delay bound.…”

In this article, an optimal design of the fractional order proportional integral derivative (FOPID) controller for time delay system is proposed. The proposed optimal design is the combined performance of both the cuttlefish optimizer (CFO) and Opposition-based learning (OBL) scheme called CFOBL scheme. The proposed CFOBL uses the concept of opposition based population initialization and opposition based position updating to improve its searching behavior, computational speed and convergence profile in the basic CFO. In FOPID controller, apart from the three tuning parameters (G P , G I , and G D ) there are two additional tuning parameters that are λ and μ. Here, CFOBL is used to tune the three controller parameters and also to find the optimal values of λ and μ. The uniqueness of the proposed technique is to reduce the FOPID controller's fault in the higher order time delay scheme by the aid of the controller's increase limits. The objective of the proposed technique is chosen by considering the set point parameters and the accomplished parameters from the time delay system. The proposed technique is used to avoid high-order delays and reliability constraints such as small overruns, time resolution and fixed condition defects. This technique is performed on the MATLAB/ Simulink platform and the results are compared with different existing techniques such as Ziegler-Nichols (ZN) tuning method, curve fitting (CF) technique, Wang technique, and regression technique.

In the present study, a homemade probe-based nanometric morphology measurement system is proposed, which can be easily integrated with other probes, such as a diamond probe and an electrochemical electrode. In this system, an intermittent-contact mode is adopted, which is based on a set of micro-force servo modules. The micro-force serve module is mainly composed of a piezoelectric ceramic transducer, a capacitive displacement sensor, an excitation piezoelectric ceramic ring, and a four-beam spring. The four-beam spring integrated with a diamond probe is driven by the excitation piezoelectric ceramic ring. The mechanical structure and the control system of the measurement system are also designed. The vibration amplitude and the resolution of a normal load are calibrated during the engagement process under open-loop control. Moreover, the optimal values for parameters P, I, and D are obtained for the closed-loop measurement. The performance of the developed system is verified by measuring a standard sample. The measured depths agree well with the results obtained by commercial atomic force microscopy. The developed system can be used to measure nanostructures with high precision.
