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…
The optimal sequence for reset controllers
Chengwai Cai, Ali Ahmadi Dastjerdi, Niranjan Saikumar +1
PID controllers cannot satisfy the high performance requirements since they are restricted by the water-bed effect. Thus, the need for a better alternative to linear PID controller…
Tuning of CgLp based reset controllers: Application in precision positioning systems
Mahmoud Shirdast Bahnamiri, Nima Karbasizadeh, Ali Ahmadi Dastjerdi +2
This paper presents the tuning of a reset-based element called "Constant in gain and Lead in phase" (CgLp) in order to achieve desired precision performance in tracking and steady…
A Frequency-Domain Stability Method for Reset Systems
Ali Ahmadi Dastjerdi, Alessandro Astolfi, S. Hassan HosseinNia
Nowadays, the demand for an alternative to linear PID controllers has increased because of the rising expectations of the high-precision industry. The potential of reset controller…
Tuning of a Class of Reset Elements Using Pseudo-Sensitivities
Ali Ahmadi Dastjerdi, Niranjan Saikumar, S. H. HosseinNia
Currently, the demand for a better alternative to linear PID controllers is increasing due to the rising expectations of the high-tech industry. In literature, it has been shown th…
Benefiting from Linear Behaviour of a Nonlinear Reset-based Element at Certain Frequencies
Nima Karbasizadeh, Ali Ahmadi Dastjerdi, Niranjan Saikumar +2
This paper addresses a phenomenon caused by resetting only one of the two states of a so-called second order "Constant in gain Lead in phase" (CgLp) element. CgLp is a recently int…
