Proportional-integral extremum-seeking control
This paper proposes a proportional-integral extremum-seeking control technique. The technique is a generalization of the standard perturbation based techniques that provides fast transient performance of the closed-loop system to the optimum equilibrium of a measured objective function. The main contribution is that the formal development of this technique does not require the need for a time-s...
متن کاملA proportional integral extremum-seeking control approach
This paper proposes an alternative extremum seeking control design technique for the solution of real-time optimization control problems. The technique considers a proportionalintegral approach that avoids the need for a time-scale separation in the formulation of the ESC. It is assumed that the equations describing the dynamics of the nonlinear system and the cost function to be minimized are ...
متن کاملProportional-Integral Extremum Seeking for Optimizing Power of Vapor Compression Systems
While traditional perturbation-based extremum seeking controllers (ESC) for vapor compression systems have proven effective at optimizing power without requiring a process model, the algorithm’s requirement for multiple distinct timescales has limited the applicability of this method to laboratory tests where boundary conditions can be carefully controlled, or simulation studies with unrealisti...
متن کاملConsensus estimation and distributed optimization over unknown time-varying networks using a new proportional-integral extremum seeking control approach
When polymeric liquids undergo large-amplitude shearing oscillations, the shear stress responds as a Fourier series, the higher harmonics of which are caused by fluid nonlinearity. Previous work on large-amplitude oscillatory shear flow has produced analytical solutions for the first few harmonics of a Fourier series for the shear stress response (none beyond the fifth) or for the normal stress...
متن کاملPhase-based Extremum Seeking Control
Extremum Seeking Control (ESC) is a model-free adaptive control method to locate and track the optimal working point for nonlinear plants. However, as shown recently, traditional ESC methods may not work well for dynamic systems. In this thesis, we consider a novel ESC loop to locate the optimal operating point for both static and dynamic systems. Considering that the phase-lag of the system un...
