On the design of sliding mode control schemes for quantum resonant converters

An evaluation of the practicality of sliding mode controllers in DC-DC converters and their general design issues

“…In particular, Mahdavi et al [17] developed the first PWM based SM controlledĆuk converter in 1996. Concurrently, the work by Huang et al [13] also generated new interests on other types of higher order DC-DC converters, namely,Ćuk, Sepic, and quantum resonant converters [20]- [23].…”

Quantum Control for an Experimental Contactless Energy Transfer System for Multiple Users

“…Quantum conversion Sliding-mode quantum conversion as a control method for resonant circuits has been treated extensively in for example [5], [6] and [7]. Quantum conversion in essence is a current pulse based switching method.…”

“…Good examples of the control method as applied in this paper (in different applications) can be found in [5], [6] and [7].…”

Indirect Sliding Mode Control of Power Converters Via Double Integral Sliding Surface

“…To ensure the existence of SM operation, the local reachability condition 0 must be satisfied. This can be expressed as (20) Case 1-Buck Converter: For the DISM voltage controlled buck converter, the existence condition for steady-state operations (equilibrium point) [8], [18], [34], can be derived by substituting (8) eration of the system's dynamics (10) as (21), shown at the bottom of the page, where denotes the minimum input voltage; denotes the expected steady-state output, i.e., approximately the desired reference voltage ; and are, respectively, the maximum and minimum capacitor currents at full-load condition; and are respectively the maximum and minimum steady-state voltage errors, which in this case are basically the inverse functions of the output voltage ripples; and and are respectively the maximum and minimum integrals of the steady-state voltage error, which is the time integral of the inverse functions of the output voltage ripples with a negligible dc shift. All these parameters can be calculated from the design specification of the converter.…”

“…These include the use of adaptive strategies [12], [30], the incorporation of constant timing functions or circuitries [7], [9], [26], and the indirect implementation of the SM controllers [14], [29], [34]. As for the second concern, it has been widely known that the steady-state errors of SM controlled systems can be effectively suppressed through the use of an additional integral term of the state variables in the SM controller [9], [14], [19], [21], [23], [25]. This method is known as integral SM control.…”
