Minimum Input Energy Trajectory Design of the Mechatronic Elevator System

Article Preview

Abstract:

The mechatronic elevator system driven by a permanent magnet synchronous motor (PMSM) is modeled by both the mechanical and electrical equations. The dimensionless forms are also derived for the purpose of practicable movements. In this paper, the minimum-input energy trajectory (MIET) and minimum control effort trajectory (MCET) based on Hamiltonian function and the five-degree (5-D) normalized polynomial trajectory are designed and compared. From the numerical simulations comparisons; it is found that the MIET has the minimum input absolute electrical energy (IAEE).
