Time regularization as a solution to mitigate quantization induced performance degradation
Bas Kieft, S. Hassan HosseinNia, Niranjan Saikumar
Reset control is known to be able to outperform PID and the like linear controllers. However, in motion control systems, quantization can cause severe performance degradation. This…
Reset band for mitigatation of quantization induced performance degradation
Bas Kieft, S. Hassan HosseinNia, Niranjan Saikumar
Reset control has emerged as a viable alternative to popular PID, capable of outperforming and overcoming the linear limitations. However, in motion control systems, quantization c…
Adaptive Feedforward Control For Reset Feedback Control Systems -- Application in Precision Motion Control
Karst Brummelhuis, Niranjan Saikumar, Jan-Willem van Wingerden +1
This paper presents a novel adaptive feedforward controller design for reset control systems. The combination of feedforward and reset feedback control promises high performance as…
Frequency-Domain Modelling of Reset Control Systems using an Impulsive Description
R. N. Buitenhuis, N. Saikumar, S. H. HosseinNia
The ever-increasing industry desire for improved performance makes linear controller design run into fundamental limitations. Nonlinear control methods such as Reset Control (RC) a…
Fractional-Order Single State Reset Element
Nima Karbasizadeh, Niranjan Saikumar, S. Hassan HosseinNia
This paper proposes a fractional-order reset element whose architecture allows for the suppression of nonlinear effects for a range of frequencies. Suppressing the nonlinear effect…
Tuning of Constant in gain Lead in phase (CgLp) Reset Controller using higher-order sinusoidal input describing function (HOSIDF)
Xiaojun Hou, Ali Ahmadi Dastjerdi, Niranjan Saikumar +1
Due to development of technology, linear controllers cannot satisfy requirements of high-tech industry. One solution is using nonlinear controllers such as reset elements to overco…
