Hardware and control co-design enabled by a state-space formulation of cascaded, interconnected PID controlled systems
In recent years, more and more attention has been
paid to the simultaneous optimization of hardware and control to
achieve an optimal design of complex and interacting systems. To
efficiently carry out this co-design optimization, there is a need
for flexible methods to apply the variable hardware and control
co-design aspects while also allowing a faster system response
calculation compared to traditional methods. These time savings
in the response calculations are of significant importance when
using iterative optimization algorithms that typically require a
large number of simulations to arrive at a solution.
That is why this paper proposes a general methodology to
create a closed-loop state-space model consisting of an open-loop
process with an observer and extensive control loop structures.
These structures comprise a combination of cascaded decentralized and distributed controllers, synchronizing controllers,
and feedforward controllers while taking into account reference
trajectories and input disturbances. It is shown that with the
proposed methodology, response calculations for a motion application are much faster compared to traditional graphical programming tools that enable to apply flexible control architecture
features. This shows that the presented methodology permits the
efficient co-design optimization of hardware en control aspects
