1. A torque converter control simulation system, comprising: a controller simulator comprising: a converter control module that integrates a slip error and determines an apply pressure value and a release pressure value based on state space feedback control including said integrated slip error and received signals including an engine torque signal, an engine speed signal, a turbine speed signal, a target slip signal and a measured slip signal; and a hydraulic control module that determines a pressure signal based on said apply pressure and said release pressure; and a mechanical simulator comprising: a hydraulic module that simulates hydraulic flow of two main valves according to a solenoid signal and based on a state space representation of the solenoid and the valves; and a mechanical module that simulates the mechanical functions of a torque converter based on torque relationships within the torque converter.
