On optimality of passivity based controllers in discrete-time

The paper deals with connections between optimality and passivity-like properties in discrete time. The problem is set in the framework of differential/difference representations of discrete-time dynamics. The Hamilton–Jacobi–Bellman equality associated with a given cost and the corresponding optimal control solution are characterized. On these bases the connection with u-average passivity is c...

Sensitivity analysis of CRA based controllers in fractional order systems

This paper focuses on robust performance analysis of a closed loop fractional order system through a sensitivity approach. The characteristic ratio assignment method is selected to attain a desired closed loop transient response. Then, we compute the sensitivity of such a desired transfer function with respect to its characteristic ratio and we explore its specifications. The relation between t...

Varinace-Based Sensitivity Analysis of Deterministic Model

‎The study of many scientific and natural phenomena in laboratory condition is sometimes impossible‎, ‎therefore theire expresed by mathemathical models and simulated by complex computer models (codes)‎. ‎Running a computer model with different inputs is called a computer expriment‎. ‎Statistical issues allocated a wide range of applications for computer expriment to itself‎. ‎In this paper‎, ‎...

Analysis for Neural Network Controllers and Passivity-Based Controller on Test System for Aero Hydraulic Pump*

Test system for Aero Hydraulic Pump (AHP) has many nonlinear characteristics. Take two control strategies, Neural Network Controller (NNC) and Passivity Based Controller (PBC), to control the speed of AHP for measuring its properties. The results gained from comparing and analyzing to these controllers show that under different outlet pressures of AHP PBC has good stability and robustness which...
