A mechanical energy exchange system, the system comprising: a first component, being a dynamic platform that imparts energy to and/or receives energy from a second component, being a load that is connected to the dynamic platform, wherein the dynamic platform and the load transfer mechanical energy to each other at one or more active points, to achieve overall energy balance in the system, wherein the first component comprises: at each of the one or more active points, one or more sensorless actuators coupled to the active point; and a controller for calculating a control vector based on multiple parameters to dynamically determine an operational mode of the mechanical energy exchange system, wherein the multiple parameters include two characteristic inter-related parameters per sensorless actuator, wherein the flow of energy at the active points at the interface of a plurality of system components is controlled by the controller, wherein the dynamic platform includes regular actuators with sensors, and the one or more sensorless actuators; wherein each sensorless actuator is associated with a two-parametric domain, where one parameter is interrelated to another parameter, such that measurement of only one parameter is sufficient to predict an output of the sensorless actuator; wherein the sensorless actuators provide real time controlled parameters for system level control using predefined calibration curves to calculate parametric values; wherein the sensorless actuators further provide two-parameter control of power at the active points, and wherein the multi-parameter control vector is a result of integration of all energy sources and loads associated with the active points; and wherein the load is adapted to transfer energy to the dynamic platform, so that energy balance is achieved at the active points. a first component, being a dynamic platform that imparts energy to and/or receives energy from a second component, being a load that is connected to the dynamic platform, wherein the dynamic platform and the load transfer mechanical energy to each other at one or more active points, to achieve overall energy balance in the system, wherein the first component comprises: at each of the one or more active points, one or more sensorless actuators coupled to the active point;
