System and method for monitoring and control

摘要: The invention provides for the monitoring and control of a system, such as linear electro-mechanical transducer, e.g. electric motor, particularly when driven in reciprocating manner. A dynamic model motor its load is used to calculate from input drive predicted response motor. compared measured parameters are varied by global optimisation until two match closely desired. may be voltage electrical current coils. variables model, after optimisation, can taken good estimates actual operating This gives measurement quantities stoke offset applicable use motors compressors, instance Stirling cycle coolers. system applied balanced pairs compressors compressor systems which an active balancer cancel vibration system. In this case created analogous way model.
