The Interconnection and Damping Assignment Passivity-Based Control Synthesis via the Optimal Control Method for Electric Vehicle Subsystems

Abstract

The interconnection between optimal control theory and the theory of energy-shaping control is described in our paper. For linear and nonlinear systems, the application of the theory of optimal control for the synthesis of parameters of energy-shaping control matrices is demonstrated in detail. The use of a Riccati equation allows us to form an optimality criterion and to synthesize the energy-shaping control system that provides the desired transient processes. The proposed approach was applied to the synthesis of control influences for electric vehicle subsystems, such as a two-mass system and a permanent magnets synchronous motor. The results of computer simulation studies, as well as those conducted on real experimental installations, are given in this paper.

Hybrid power management and control of fuel cells‐battery energy storage system in hybrid electric vehicle under three different modes

“…It is therefore assume given (37) and definition that P e represented in Equation ( 29) is supposed to be purely passive, hence the term pω m R À1 dq ψ T dq Iψ dq is characterized as workless forces component since it has no impact on Equation (42) which indicates the energy balance. ▪…”

“…In this paper, a new control strategy, adopting passivity theory to realizing an optimal torque and track velocity is investigated. Passivity‐based control (PBC) offers multiple essential benefits, including the damping of nonlinear terms instead of their elimination, promised stability, and claimed robustness 36,37 . The control strategy uses the principle of the cascade control based on the decomposition of an initial drive control problem on the drive processes.…”

Increasing the Level of Autonomy of Control of the Electric Arc Furnace by Weakening Interphase Interactions

“…Quite simply, the problem of compensating the mutual influences is solved by the method of energy-forming control [17,18]. Thus, when applying IDA passivity-based control [19,20], the control influences are obtained by forming the desired interconnections and damping. The choice of the matrix of interconnections and damping ensures the target correction of processes in the controlled object.…”

Arc Voltage Distortion as a Source of Higher Harmonics Generated by Electric Arc Furnaces

“…The knowledge of the arc model is necessary to determine the optimal operating point of the arc device, i.e., ensuring the maximization of the arc power during scrap melting [1,2]. The stabilization of the operating point is achieved through the use of electrode shift control systems, which use algorithms dependent on the adopted arc model [3,4].…”
