Self learning control system and method for optimizing a consumable input variable

A method for controlling one or more operable elements resulting in output variables, at least one of the operable elements including a respective variably controllable motor, wherein there is more than one operation point or path of system variables that can provide a given output setpoint, wherein at least one system variable at an operation point or path restricts operation of another system variable at the operation point or path, the method comprising:

• performing a control loop comprising:
• detecting input variables, the input variables including non-controllable variables and system controllable variables, the non-controllable variables including output demand, the system controllable variables include a speed of at least one of the variably controllable motors and at least one optimizable input variable, the at least one optimizable input variable including power consumed,
• detecting the system variables,
• updating a model with respect to the at least one optimizable input variable, comprising calculating the updated model using established relationships between variables, the detected input variables and the detected system variables, the updated model providing, based on established relationships between variables, prediction of use of the input variables in all possible operation points or paths of the system variables which achieve an output setpoint, and
• operating, based on one or more of the detected input variables and the detected system variables, the one or more operable elements in accordance with the updated model to provide an optimal operation path of the system variables which achieves the output setpoint and which optimizes consumption of the at least optimizable one input variable;
• wherein for iterations of the control loop said updating of the model is based on said operating of the one or more operable elements during the control loop;
• and
• determining that one of the operable elements is performing off of the model.
