摘要

作者提出了一种基于无差拍控制和参数估计的脉冲宽度调制电流逆变器的实时信号处理方法。在电压和电流采样的无差拍控制和电流采样的无差拍控制中，采用了一步超前控制策略。采用离散根轨迹法分析了控制器的稳定性，采用最小二乘法估计了负载参数。考虑了采样时间为8.33 μ s的4 kHz电流馈电逆变器。给出了计算机仿真结果。

Medium frequency deadbeat controlled PWM inverter with parameter estimation for induction heating

The authors propose real-time signal processing based on deadbeat control of a pulsewidth modulation (PWM) current inverter with parameter estimation for induction heating applications. The one-step-ahead controller strategy is used in deadbeat control with voltage and current sampling and in deadbeat control, with current sampling. The controllers' stability is analyzed by the discrete root locus method and the load parameters are estimated by the least squares method. A current-fed inverter of 4 kHz with a sampling time of 8.33 mu s is considered. Computer simulation results are presented.<>
