Abstract
A method of controlling a mechanical actuator using a modular map processor comprises monitoring a plurality of parameters associated with the actuator. The modular map processor generates a control signal based on the parameters for output to the actuator and modifies the control signal based on a merit function. In preferred forms the mechanical actuator is an input or output valve in a cylinder for an internal combustion engine.
Claims8
A method of controlling a mechanical actuator comprising the steps of monitoring a plurality of parameters relating to the system associated with the actuator and using a modular map processor to control the actuator.
Apparatus for controlling valve gear of an internal combustion engine, comprising a plurality of sensors for sensing a plurality of parameters selected from actuator position, actuator velocity, operation timing, temperature and pressure, and at least one modular mapping circuit means connected to receive sensor signals representing said parameters and operable to generate at least one control signal for controlling at least one mechanical actuator which forms at least part of said valve gear.
