Abstract

The implementation of large linear control systems requires a high amount of digital signal processing. Here, we show that re-configurable hardware allows the design of fast yet flexible control systems. After discussing the basic concepts for the design and implementation of digital controllers for mechatronic systems, a new general and automated design flow starting from a system of differential equations to application-specific hardware implementation is presented. The advances of reconfigurable hardware as a target technology for linear controllers is discussed. In a case study, we compare the new hardware approach for implementing linear controllers with a software implementation.
