响应速度快、效率高、可靠性好是电动汽车用DC/DC变换器的重要特性。两级DC-DC变换器是一种能够为电动汽车提供这些特性的DC-DC拓扑。非线性控制是目前直流-直流变换器控制算法研究的一个活跃领域。然而，很少有文献研究电动汽车的两级变换器。针对两级DC-DC变换器，提出了固定开关频率滑模控制器和双积分滑模控制器。并选择传统的线性控制（滞后）作为比较。所提出的FSFSM控制器的性能进行了比较与滞后控制器所获得的。仿真和实验结果表明，FSFSM控制器能够提供良好的大信号操作和快速的动态响应的转换器。最后，通过仿真结果证明了DISM控制器是一种有效的消除稳态误差的方法。
The fast response, high efficiency, and good reliability are very important characteristics to electric vehicles (EVs) dc/dc converters. Two-stage dc-dc converter is a kind of dc-dc topologies that can offer those characteristics to EVs. Presently, nonlinear control is an active area of research in the field of the control algorithm of dc-dc converters. However, very few papers research on two-stage converter for EVs. In this paper, a fixed switching frequency sliding mode (FSFSM) controller and double-integral sliding mode (DISM) controller for two-stage dc-dc converter are proposed. And a conventional linear control (lag) is chosen as the comparison. The performances of the proposed FSFSM controller are compared with those obtained by the lag controller. In consequence, the satisfactory simulation and experiment results show that the FSFSM controller is capable of offering good large-signal operations with fast dynamical responses to the converter. At last, some other simulation results are presented to prove that the DISM controller is a promising method for the converter to eliminate the steady-state error.
