New PID parameter autotuning for nonlinear systems based on a modified monkey–multiagent DRL algorithm

H Zhang, W Assawinchaichote, Y Shi - IEEE Access, 2021 - ieeexplore.ieee.org
Proportional–integral–derivative (PID) control is the most widely used control law in
industrial processes. Although various new controllers continue to emerge, PID controllers …

Optimal design of a nonlinear control system based on new deterministic neural network scheduling

W Assawinchaichote, J Pongfai, H Zhang, Y Shi - Information Sciences, 2022 - Elsevier
In this paper, a new deterministic neural network scheduling is proposed to optimally design
the controller of a nonlinear system. The new deterministic neural network scheduling can …

Event-triggered fuzzy integral control for a class of nonlinear singularly perturbed systems

A Visavakitcharoen, W Assawinchaichote, Y Shi… - ISA transactions, 2023 - Elsevier
A fuzzy integral controller with an event-triggered strategy for a class of nonlinear continuous
singularly perturbed systems is proposed in this manuscript. Since the singularly perturbed …

Improved MM-MADRL algorithm for automatic tuning of multiparameter control systems

H Zhang, W Assawinchaichote, Y Shi - IEEE Access, 2022 - ieeexplore.ieee.org
Control systems are widely used in our lives, and good control can be achieved by obtaining
the optimal tuning parameters of the control system. The number of parameters that need to …
