Читать книгу Control of Mechatronic Systems - Patrick O. J. Kaltjob - Страница 24

Mechatronic systems and processes have built-in intelligence through either their advanced information processing systems such as multifunctional control systems or intelligent electromechanical systems (including thermal, fluid, and mechanical processes) such as power-efficient multi-axis actuation with motion precision and detection features or miniaturized smart devices with embedded information processing capabilities. The resulting controlled mechatronic systems and processes aim to achieve various objectives: synchronize, control and sequence process operations, or detect and monitor process status.

Table 1.1 presents some typical process control objectives and their corresponding control functions along with some illustrative examples.

Table 1.1 Functions and implementation strategies for controlling mechatronic systems and processes.

Control system processing functions	Implementation control strategies	Examples of controlled mechatronic systems and processes
Assessing, reporting, and monitoring	Recording process variables through sensors and detectors; real-time, model-based measurement, setting parameters, and input signals.	Remote power flow measurement, configuration and voltage control (SCADA) through switchgears, transformers, and condensers in a smart power grid.
Safety compliance, detection, and diagnostics	Interlocking in case of detected failure modes, maintaining safety operations while ensuring malfunction handling.	Integrated safety and monitoring of petrochemical process variables and parameters (flowrate, temperature etc.)
Control and performance enhancement	Controlling or regulating system variables.	Position and temperature measurement as well as control of a 2D cutting machinery process.
