For example, say you are driving the solenoid directly from a As there is no feedback the system is unable to respond to changing/fault conditions.Never reach the barrel, set it too slow/long and the solenoid could overheat The solenoid & spring must stay the same if you want reliable operation.įor example set the pulse too fast/short and the firing pin would The constant frequency/duty pulse must be carefully tuned, and once tuned Doing things this way is easy but as one might expect has some disadvantages, a couple of which are: World this would be considered an open-loop system. With the current AR2 prototype I am driving the solenoid with aĬonstant frequency/duty pulse, as there is no feedback in the engineering In this post I go over my current solenoid/firing pin control methodology
