“…The new wanted polynomial expression is given in (24) According to the control theory [31,32], in order to place the closed-loop poles in any desired place, the controller must have a number of coefficients equal to the number of the closed-loop poles. Therefore, a PI with just two coefficients is not enough.…”

“…The three highest maximum speeds reported in the previously cited works are 288 rpm for [11], 380 rpm for [12] and 450 rpm for [22], whereas in this paper 1320 rpm is the highest maximum speed reported. To achieve such goal, firstly, the need of surpassing the widely used traditional proportional and integral (PI) controller [24,25] is justified and secondly, a new second-order controller is designed and tuned in z domain, which brings the possibility to properly compensate the processing delays as well as the pulse width modulation (PWM) of the power electronics actuator. Such proposed high bandwidth (BW) controller has envisaged, from the very beginning, the industrial feasibility for further commercialization.…”

This paper pursues to maximise the mechanical speed when using stepping motors (SM) without position sensors in order to achieve a rapid-response manufacturing whenever any equipment based on such electrical machines is involved. The novelty of this paper is the fact that not only the bandwidth of the current controllers is improved for such maximization of the SM mechanical speed, as traditionally done in previous works, but also a comprehensive approach has been addressed. Such global approach starts justifying why the traditional PI controller is not sufficient and it includes the analytical tuning of the current controllers, considering implementation tiny issues (but of paramount importance) such as the delays caused by the processor and the sample and hold current measurements. It is proved and justified that this previously mentioned issues, which are often omitted, play a crucial role when trying to maximise the speed of the SM, since the electrical fundamental frequencies of the SM move close to the sampling frequency. Therefore, the analytical process to tune and implement the current controllers will have to be done in discrete-time domain, i.e. using the Z transform and treating the SM drive as a sampled data system. Experimental waveforms and results based on real prototypes will prove the validity of the entire research. Finally, a real case-study based on Printed Circuit Board (PCB) prototyping machine which is composed by two stepper machines, is fully reported. Such PCB prototype is the fruitful collaboration between the University (research institution) and a private company (industry). © 2016 Elsevier LtdPeer ReviewedPostprint (author's final draft

“…[ 31 ] A performance‐optimal piecewise affine variable‐gain feedback controller was introduced to circumvent performance‐limiting trade‐offs encountered in the control of linear motion systems. [ 32 ] A gradient descent method–based delay estimator was proposed for networked control systems with a variable gain control strategy. [ 33 ] An extremum‐seeking control strategy was designed for the adaptive design of variable‐gain controllers which balanced the tradeoff between low‐frequency disturbance suppression and sensitivity to high‐frequency noise in a more desirable manner.…”

Summary As the auxiliary mass of an active mass damper/driver (AMD) control system in a high‐rise building has excessive strokes and its relative velocities are in the same direction with the strokes, the auxiliary mass probably collides with its anti‐collision device. As a result, the structural responses increase and even the structural safety is endangered. In this paper, a variable gain state‐feedback control system is proposed to limit the strokes and relative velocities of the auxiliary mass, so as to ensure the safety of the system. Firstly, the limited state of the auxiliary mass is defined, and a regional pole assignment algorithm that utilizes only a damping factor is realized as a control gain. Then the relationship between the control gain corresponding to the stroke and its threshold limit value is deduced. A suitable threshold limit value is chosen to reduce the strokes and the relative velocities. Finally, the performance characteristics of the control systems with or without stroke limit are analyzed. The results demonstrate that the controller limits the strokes effectively on the premise of guaranteeing the control effects and the AMD parameters. To verify its effectiveness, the proposed methodology is also applied to an experiment of a four‐storey frame.
