This way doesn't need to add relaycharacteristic, it can realities to self setting up PID parameter.
该方法无需加入继电器特性即可实现PID参数自整定。

Their design is based on the use of analogue electronic devices instead of coils and magnets to create the relaycharacteristic.
其设计的基础上，而不是创建继电器特性的线圈和磁铁的模拟电子设备的使用。

This paper introduces a way to predict the electric oven's parameter. This way doesn't need to add relaycharacteristic, it can realize to self setting up PID parameter.
