“…Voltage command tracking capability is shown in Table 2 on sixth column (settling time, t s ). Shirazi et al (1) showed the settling time 800 μs for switching mode power supplies. Oettmeier et al (14) proposed a model predictive controller (MPC) with a sliding mode observer for portable electronic devices, and reported settling time 1700 μs for voltage change 165 V to 175 V. This paper reports 280 μs settling time for a converter applied in servomotor applications.…”

“…The performance of DC-DC converters may be evaluated by two kinds of performance index: (1) the command voltage tracking capability and (2) robustness to the disturbances (1) . Among several DC-DC converters, the boost type has an unstable zero in the plant, thus it is said to have difficulties in higher performance.…”

“…Among several DC-DC converters, the boost type has an unstable zero in the plant, thus it is said to have difficulties in higher performance. Based on the literature survey on boost type converters, Shirazi et al (1) proposed an online tuning control based on the system-identification algorithm called PRBS (pseudo random binary sequence) perturbation (2) . After the plant parameters are identified online, a digital PID controller regulates the output voltage.…”

This paper proposes a fast and robust nonlinear deadbeat control for boost DC-DC converters. First, the nonlinear state equation is derived, and second a nonlinear current reference deadbeat control is proposed. Third, a new nonlinear controller to implement the load disturbance compensation is proposed. After the simulations and verification by experiments, it was confirmed that under the conditions of an input voltage of 12 V, an output voltage of 20 V, a load resistance of 4 Ω and a sampling frequency of 100 kHz, the voltage command tracking capability of a settling time of 280 μs was achieved, and an output voltage recovery time of 1.46 ms was achieved for a sudden load change.

Auto-tuning proportional-integral-derivative (PID) controller improves the dynamic response of a switching converter. In this paper, a robust H∞ synthesis approach is proposed to design an auto-tunable PID controller for buck converters. Through the proposed H∞ approach, the PID controller is parameterized by a tunable parameter behaving like a 'knob' on the closed-loop performance. Simulations show the closed-loop characteristics. Practical experiments confirm the dynamic response improvement, with a comparison of a parameter fixed PID controller by zero-pole placement. , vol. 24, no. 11, pp. 2578-2588, 2009.
