Abstract

This paper first presents theoretical research on direct optimization using the Rotate-Vector (RV) Algorithm which is suitable for the complex objects and valuable in engineering applications with global optimization ability. The derivation of the RV algorithm is illustrated in three-dimensional space and subsequently extended into multi-dimensional space. The numerical simulation utilizes this RV algorithm to optimize the parameters of a Proportional-Integral-Differential (PID) controller for an electro-hydraulic system. Simulation results show that the RV algorithm can solve optimization problems without calculating the function gradient.
