Measurement, Control and Regulation Technology
The metrology is concerned with devices and methods for measuring physical variables (eg, length, mass, force, pressure, flow, temperature or time) and is for the most accurate control or regulation of great importance. The control technology is based on the measurement technology. It is characteristic of the control technology that the physical quantities, influenced by actuators, not react on measured metrics. This always creates an open action path, which is also referred to as an open control chain. The control technology on the other hand extends the process control technology. This extension consists of a feedback of the influenced quantity to form a closed control loop. Apart from simple PID controllers, we have knowledge and expertise in additional control technology. State Control with (state-)observers, sensor fusion by Kalman filter, algebraic derivative estimation procedures or non-linear control technology approaches such as the flatness-based trajectories sequence control, backstepping, sliding mode or Model -Predictive Control (MPC) offer the potential to significant increases in performance in your application. Experience has shown that a state controller increases the rise time (t90) by a factor 3 in heavily deadtime systems compared to a PID controller.
