“…There are two possible ways of measuring the clutch motion directly: by measuring the clutch piston displacement or measuring the pressure inside the clutch chamber. In [12][13][14][15], the authors have shown satisfied results with the displacement feedback. Song and Sun [16] also given promising results with the pressure in the chamber as a feedback signal.…”

“…Proportional-integral-derivative control methods [11][12][13] were used to control the pressure of pneumatic systems. In [5], a dual-mode controller was proposed for an electro-pneumatic clutch actuator with on/off solenoid valves. In [14], a hybrid control algorithm was adopted for pneumatic actuators.…”

Pneumatic brake systems are crucial for the operation of trains. However, due to switching characteristics of on/off solenoid valves, the precise pressure control and low switching activities of valves are difficult to guarantee simultaneously during braking. To address the issue, a hybrid model predictive control (MPC) method is proposed for implementing the multi-objective optimisation in this paper, i.e. the precise pressure tracking and the valve switching reduction. In order to model the hybrid behaviour caused by continuous dynamics of the pressure and discrete features of solenoid valves, the mixed logic dynamical system theory is applied. Then, the braking control problem is recast as a hybrid MPC problem, which jointly optimises the pressure tracking precision and the valve switching. A mixed integer linear program is formulated to solve the MPC problem in an efficient way. Both simulation and experiment results show that the accurate pressure control and low switching activities of valves can be achieved by the proposed method when compared with existing methods.

“…However, instead of SMC, a model-based backstepping controller is used. The authors of [24] show a dual-mode controller for an electro-pneumatic clutch actuator, which is a combination of a local and a global switched controller. In [25], a switched backstepping control of an electro-pneumatic clutch actuator is presented, showing better performance than PWM-based methods and also using less solenoid valve switches.…”

The paper presents the modeling and control design of a floating piston electro-pneumatic gearbox actuator and, moreover, the industrial validation of the controller system. As part of a heavy-duty vehicle, it needs to meet strict and contradictory requirements and units applying the system with different supply pressures in order to operate under various environmental conditions. Because of the high control frequency domain of the real system, post-modern control methods with high computational demands could not be used as they do not meet real-time requirements on automotive level. During the modeling phase, the essential simplifications are shown with the awareness of the trade-off between calculation speed and numerical accuracy to generate a multi-state piecewise-linear system. Two LTI control methods are introduced, i.e., a PD and an Linear-Quadratic Regulators (LQR) solution, in which the continuous control signals are transformed into discrete voltage solenoid commands for the valves. The validation of both the model and the control system are performed on a real physical implementation. The results show that both modeling and control design are suitable for the control tasks using floating piston cylinders and, moreover, these methods can be extended to electro-pneumatic cylinders with different layouts.
