Mosaic's embedded controllers offer a high level of software/hardware integration for PID control

Proportional-Integral-Derivative (PID) control is a widely used technique in industrial control applications. PID is a software routine run by the microcontroller's processor. Its purpose is to correct or minimize the error between a measured process variable and a target value, for example, a measured temperature versus a temperature setpoint targeted by an HVAC control system.

The PID algorithm involves 3 separate parameters: the Proportional (gain); the Integral (reset); and the Derivative (the rate of change during a given interval). The PID algorithm is used for the control of almost all loops in the process industries. In order for control loops to work properly, the PID loop must be properly tuned. Based on the PID control loop feedback algorithm, the embedded controller tunes the process and eliminates process disturbances by continuously moving the output towards the setpoint. The tuning is based on the dynamics of the process response, i.e. on comparing the target value to the measured feedback.

PID loops implement customizable control of any measurable variable, be it temperature, flow rate, pressure, or speed. Special software can perform calculations to make PID design easier.

The custom firmware provided with Mosaic embedded controllers
make PID control a snap.
