二、移位型状态控制器的设计移位型状态控制器是用一个触发器的状态表示被控制系统的一个状态。如果系统有N个状态,就用N个触发器。例如第ⅰ个触发器表示系统的第ⅰ状态,那末系统在第ⅰ状态工作时,只有第ⅰ个触发器被“置位”,而其他触发器皆处于“复位”状态。这种工作方式正好与移位寄存器移一个“1”电平的工作方式相似,因此称它为移位型状态控制器。可以根据状态转移条件不按顺序地发生状态变化。 Second, the displacement of the state controller design Shift state controller is a state of the trigger that a controlled system state. If the system has N states, use N triggers. For example, the ith trigger indicates the ith state of the system. When the system is operating in ith state, only the ith trigger is “set” and all other triggers are in the “reset” state. This works exactly the same way as a shift “1” shift register, so it is called a shift state controller. The state changes can occur out of order according to the state transition conditions.
