DSP  AD5435 Engine Setpoint Controller

Engine Control for Component Development and Testing

The AD5435 is an ideal system for a wide variety of engine control applications, particularly for component development, testing and/or investigation.

Full User Control

In many test cell applications it is often difficult - and sometimes impossible - to modify or calibrate the algorithms of an OEM, development or aftermarket ECU. With the AD5435, SimulinkR software provides the capability to manipulate algorithms, giving the user complete control over the engine. The use of Simulink eliminates the need for embedded software or special programming. There is no complex setup, advanced training or operating system expertise required, making this an ideal tool for both engineers and test cell operators who work with engines.

Open & Extensible System

With a variety of optional cards available, the AD5435 can be configured for a wide range of applications, from simple open loop fuel injection pulse width control to more sophisticated closed loop control algorithms of all engine systems. A&D Technology offers both turnkey and user-defined systems. In either case, the AD5435 provides the user complete control of the software and hardware components, as well as the graphical interfaces needed to operate the system.
