In increasingly complex systems, it is becoming increasingly difficult to accurately identify the location of failures and the extent of their effects. Chaos engineering is a method to improve the reliability of the system by causing failures to reveal the problems. In this study, we propose a method of reset control that suppresses the failure of a pneumatic control valve by simulating the failure of the valve, incorporating the concept of chaos engineering. In this study, in order to investigate a new control method for the control parts of the positioner, simulations are conducted in which a chaotic signal is superimposed as a simulated disturbance on the input signal of a mathematical model of a pneumatic control valve with an electronic positioner. As an appropriate control method for control parts of the positioner, we apply the reset control, which autonomously generates pulses from the control deviation as a feedback control. The parameters of the reset control are adjusted for this model, and the simulation results show this reset control with these parameters can suppress failures caused by the superimposition of simulated chaotic signals.
