Design of Hysteresis Control based Adaptive Sliding Mode Control and Cuckoo Search based PI Control for DC-DC Boost Converters

Due to the underlying complexities and nonlinear behavior of the DC-DC boost converters, its control becomes a difficult operation. The non-minimum phase behavior of the DC-DC boost converters also makes it tough to control. This paper proposes two different techniques based on hysteresis based Adaptive SMC and Cuckoo Search (CS) based Proportional-Integral (PI) control methods for controlling DC-DC boost converters. The two techniques applied in this research are compared in terms of various performance indices such as Integral of Absolute Error (IAE), overshoot, rise time and settling time. The effectiveness of the two proposed controllers are evaluated in relation to changes in input voltage, reference voltage and load. The two proposed methods are also compared against a conventional PID tuned by Internal Model Controller (IMC). The hysteresis control based adaptive sliding mode controller performs better than CS based PI controller and IMC based PID controller with lesser IAE against fluctuations in terms of reference voltage, load, and input voltage.
