Controller Algorithm With Integrated Switching Technology

ExpertControl Controller Switching Technology (ecCST) is a flexible software feedback-control algorithm available as a ready-to-use VI for NI LabVIEW software. Besides providing various controller structures suitable for almost any kind of applications and the worldwide unique Controller Switching Technology, ecCST is fully parameterized automatically by ExpertControl Intelligent Controller Parameterization (ecICP) software.

ecICP is available as a toolkit for LabVIEW. It automatically calculates the optimal parameters within a model-based control design approach for the ecCST control algorithm or even customer-specific controller structures up to PID, based on measured or simulated data.

Engineers, scientists, and technicians who are using LabVIEW for any control logic and feedback-control applications, such as the following, benefit from easy-to-use handling and powerful control capabilities if they supplement LabVIEW with ecICP and ecCST:

  • Test engineering
  • Test bench automation
  • Research and development
  • Industrial process automation
  • Implementation and debugging

In many cases, delays in completion, penalty costs, or even call-back costs are the result of bad parameterized feedback controllers. To realize good control behavior, time-consuming calculations and expert knowledge are usually necessary. The reasonable alternatives to these expensive factors are easy-to-use control design software tools from ExpertControl called ecICP for NI LabVIEW and ecCST for NI Hardware.

Improving the Design Process With ecCST

Realizing high-complex feedback-control applications with ecICP and ecCST in LabVIEW is simple. No complex calculations or expert knowledge is needed to design feedback controllers that yield desired closed-loop behaviors.

LabVIEW and NI hardware provide measured data from technical systems. As depicted in Figure 2, this measured data constitutes the basis for the ecICP model-based control design approach. With information about system dynamics from measurements and additional information about desired transition times from users, ecICP completely and automatically executes the complex calculations that are necessary for system identification and feedback-control design.

Within a few seconds rather than days or weeks, ecICP provides model and controller information such as transfer functions, state space models, set-point filters, and controller structures with their suitable parameters for standard and even high-complex systems within an ecICP result file. Realizing individually different controller settings with one control algorithm requires high flexibility. Only ecCST is capable of providing such a flexible control algorithm to realize simple PI controllers, special ramp controllers, or even fifth-order state controllers with observers and a decoupling unit for multiple input, multiple output (MIMO) systems.

However, to define the necessary controller structures of ecCST, no programming is necessary. As soon as the ecICP result file is available in LabVIEW, the ecCST control algorithm knows exactly which controller setting is required for which operating area.

Figure 2. How to Use ecICP and ecCST:
1. Capture measured data with LabVIEW; 2. Import measured data to ecICP; 3. Create models and controllers automatically; 4. Transfer ecICP result file to target to let ecCST know what kind of controller is required.

With the extreme flexibility of ecCST and the highly efficient and easy-to-use parameterization tool ecICP, users can apply this toolchain to all kinds of technical systems where LabVIEW is used as the development and control environment. Regardless of application areas such as test bench automation or research and development, LabVIEW users do not need further control and development environments in terms of modeling and control design with the supplemental capabilities of ecICP and ecCST. This saves expensive license costs and valuable development time as well as increases the quality of technical processes and the reliability of the products.
