Answer:
PID Controller
Step-by-step explanation:
Known for its stability and efficiency, the PID (proportional integral derivative) controller would be the best type of controller used in this case.
Remember, a controller basically is a name attributed to the device architecture that allows the controlling of temperature, pressure, and flow processes.
Hence, since there is a lot of noise in the shampoo manufacturing system, having persistent errors which happen suddenly, the use of a PID Controller should able to detect and resolve the issue.
