TL;DR: In this paper, a detailed study of a method of rotor-resistance estimation for indirect-field-oriented control of induction machines based on the reactive-power reference model is presented, and the estimation procedure can be carried out independently of the stator frequency and the load torque.

TL;DR: For the parameters of the physical platform two studies are presented to demonstrate that the single lumped mass model is a proper description of the system even in situations in which the link mass is up twice bigger than the payload mass.

TL;DR: A control system that combines a fractional-order D tip position controller with a feedforward force control that attains higher stability robustness and higher phase margin than a PD controller, which is the integer-order controller of similar complexity is proposed.

TL;DR: In this paper, the design and application of selective controllers for voltage-source-inverter output control in single-phase and three-phase applications are investigated, and the closed-loop stability of the resulting systems is investigated thoroughly and the controller design process is explained from the frequency-response viewpoint where stability margins can be designed explicitly.

TL;DR: A theorem is proposed that defines the structure of the set of controllers that fulfil these specifications and shows that it is necessary for these robust controllers to include a fractional-order P I term.
