“…This was applied in the air intake system of diesel engines in [28] and in the time-variant parameter identification of gasoline engines in [29]. In [30,31], a LPV-based scheduling method, specific to wetted wall engine parameters and engine speed time-variant parameters was put forward. By utilizing group design of PID and PID control parameters, the control problem of the influence of time-variant parameters to the nominal model during dynamic processes could be solved.…”

Abstract:The common rail pressure has a direct influence on the working stability of Opposed-Piston Two-Stroke (OP2S) diesel engines, especially on performance indexes such as power, economy and emissions. Meanwhile, the rail pressure overshoot phenomenon occurs frequently due to the operating characteristics of OP2S diesel engines, which could lead to serious consequences. In order to solve the rail pressure overshoot problem of OP2S diesel engines, a nonlinear concerted algorithm adding a speed state feedback was investigated. First, the nonlinear Linear Parameter Varying (LPV) model was utilized to describe the coupling relationship between the engine speed and the rail pressure. The Linear Quadratic Regulator (LQR) optimal control algorithm was applied to design the controller by the feedback of speed and rail pressure. Second, cooperating with the switching characteristics of injectors, the co-simulation of MATLAB/Simulink and GT-Power was utilized to verify the validity of the control algorithm and analyze workspaces for both normal and special sections. Finally, bench test results showed that the accuracy of the rail pressure control was in the range of ±1 MPa, in the condition of sudden 600 r/min speed increases. In addition, the fuel mass was reduced 76.3% compared with the maximum fuel supply quantity and the rail pressure fluctuation was less than 20 MPa. The algorithm could also be appropriate for other types of common rail system thanks to its universality.

“…LPV gain-scheduling control [35] was used to control the engine air-to-fuel ratio (AFR) [32], variable valve timing (VVT) actuator [33], and engine throttle position [34]. The advantage of the LPV control is that the parameter dependent gains can be obtained during the control design, which eliminates (or significantly reduces) the control calibration effort.…”

This paper introduces the needs for applying model-based control techniques to vehicle powertrain and aftertreatment systems. A tutorial overview of model-based control techniques and methodologies for modern powertrain and aftertreatment systems is presented and compared with the traditional approaches. The control-oriented powertrain and aftertreatment system modeling techniques are also addressed along with their real-time simulation requirement for HIL (hardware-in-the-loop) simulations. The application examples of the model-based control of internal combustion engine, transmission, and aftertreatment systems are given in detail.Guoming Zhu is with the Department of Mechanical Engineering and the
