This paper describes the modeling, controller development, and implementation of a transmission clutch pressure control system. A nonlinear analytical model for the clutch pressure control system is developed and implemented using Matlab/Simulink, and validated by experimental data. The dominant dynamics are identified via model analysis, and a linear model is derived for controller design. Openloop (feedforward) and closed loop (feedback) pressure control strategies are designed and implemented in a test setup. Experimental results show that the combined feedforward and feedback control gives superior performance as compared to feedforward control alone.
