研究了由第二代电流传输器（CCII）产生的多向多涡卷混沌吸引子。通过在高阶Jerk系统中设计阶梯函数和移位电压符号函数，分别构造了四阶和五阶网格多涡卷混沌系统。利用CCII设计并实现了一个混沌电路，通过开关控制，该电路可以分别产生4 × 2 × 2 × 2和4 × 2 × 2 × 2 × 2涡卷混沌吸引子.与基于电压运算放大器的电路相比，该电路在电路结构和带宽方面具有更好的性能。数值模拟结果与实验结果一致。
The multidirectional multiscroll chaotic attractors generated by second-generation current conveyor (CCII) are investigated. A fourth-order and a fifth-order grid multiscroll chaotic system are presented by designing staircase function and shifted voltage sign functions in the high-order Jerk system. Using the CCIIs, a chaotic circuit is designed and implemented, which can generate 4 × 2 × 2 × 2- and 4 × 2 × 2 × 2 × 2-scroll chaotic attractors, respectively, via switching control. Compared with the voltage operational-amplifier-based circuit, the proposed circuit has better performance in terms of circuit structure and bandwidth. Numerical simulations and experimental results are accordant.
