  PID controllers cannot satisfy the high performance requirements since they
are restricted by the water-bed effect. Thus, the need for a better alternative
to linear PID controllers increases due to the rising demands of the high-tech
industry. This has led many researchers to explore nonlinear controllers like
reset control. Although reset controllers have been widely used to overcome the
limitations of linear controllers in literature, the performance of the system
varies depending on the relative sequence of controller linear and nonlinear
parts. In this paper, the optimal sequence is found using high order sinusoidal
input describing functions (HOSIDF). By arranging controller parts according to
this strategy, better performance in the sense of precision and control input
is achieved. The performance of the proposed sequence is validated on a
precision positioning setup. The experimental results demonstrate that the
optimal sequence found in theory outperforms other sequences.
