PID controllers, when used alone, can give poor performance when the PID loop gains must be reduced so that the control system does not overshoot, oscillate or hunt about the control setpoint value. They also have difficulties in the presence of non-linearities, may trade-off regulation versus response time, do not react to changing process

For systems with poorly damped dynamics, the choice of derivative factor cd must be modiﬁed. Systems with small relative damping combined with small relative timedelay L/T are not feasible to design PID controllers for, using the methods described in this article, so only mildly oscillative systems are considered.

system() executes a command specified in command by calling /bin/sh -c command, and returns after the command has been completed You can go into the background within the command/script you're executing (and return immediately), but I don't think there's a specific provision in system for that case. 2020-10-28 · PID control is applicable to many control actions but it does not perform well in case of optimal control. Main disadvantage is the feedback path. PID is not provided with any model of the process.
