A Fast-Response Sliding-Mode Controller for Boost-Type Converters With a Wide Range of Operating Conditions

Abstract

Abstract-This paper proposes a fast-response sliding-mode controller for controlling boost-type converters requiring a fast dynamical response over a wide range of operating conditions. The various aspects of the controller, which include the method of generating the reference-current profile, the choice of sliding surface, the existence and stability properties, and the selection of the control parameters, are discussed. Experimental results are presented to validate the theoretical design and to illustrate the strength of the proposed controller. It is demonstrated that, with the proposed controller, the boost converter has a faster response and a lower voltage overshoot over a wide range of operating conditions as compared to that under the widely used peak current-mode controller. Moreover, it is easily realized with simple analog circuitries.

Design of Sliding-Mode-Observer-Based Sensorless Control of Boost Converters for High Dynamic Performance

“…1, for a single-loop output-voltagecontrolled boost converter in the CCM, neither a linear controller such as a PID [20] nor a nonlinear controller such as a sliding mode controller [21] can maintain good dynamic performance because of the RHPZ in the transfer function from the duty ratio to the output voltage. Doubleloop current control [20] or a controller using the inductor current as a system state in the time domain [21] is widely adopted to maintain good dynamic performance; however, the inductor or switch current should be sensed, as shown in Fig. 2, which illustrates a double-loop current control.…”

Synergetic Control of a Hybrid Battery-Ultracapacitor Energy Storage System

“…During the last decade, different control techniques based on adaptive control theory, sliding mode control, fuzzy logic, and neural networks have been proposed for the control of DC-DC power converters [18,19]. The main objective of such nonlinear controllers is to provide the control support for boost-type converters to improve their controllability and performance for large operating ranges.…”

Robust Delay-Independent/Dependent Stabilization of Uncertain Time-Delay Systems by Variable Structure Control

“…In survey paper (Hung et al, 1993) the various type of reaching conditions, variable structure control laws, switching schemes and its application in industrial systems is reported by J. Y.Hung, Gao and J.C.Hung. The implementation of a tracking variable structure controller with boundary layer and feed-forward term for robotic arms is developed by Xu, Hashimoto, Slotine, Arai and Harashima (Xu et al, 1989).A new fast-response sliding mode current controller for boost-type converters is designed by Tan, Lai, Tse, Martinez-Salamero and Wu (Tan et al, 2007). By constructing new types of Lyapunov functionals and additional freeweighting matrices, some new less conservative delay-dependent stability conditions for uncertain systems with constant but unknown time-delay have been presented in (Li et al, 2010) and its references.…”
