Here we show that reconfigurable 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. Keywords and phrases digital linear control reconfigurable hardware mechatronic systems. 1. INTRODUCTION Modern controller design
