Since the controller obtained is a function of mode coordinate, an extraction method of modal coordinate from actual physical measurements is developed.
For these computations, we use finite differences to discretize the time coordinate, a discrete ordinate method to discretize the directional variable, and an expansion in radial basis functions to approximate the spatial dependence of the solution.
Taking material parameters involved in Norton's law to be the functions of the radial coordinate, a simple and accurate method is developed from the strain rate stress relations, Norton's law, deformation compatibility condition and equilibrium equation of axisymmetric, plane strain problems.
The CHP and thermostatically controlled loads are coordinated by a method with two different time scales in order to execute the schedule and handle uncertainties from the load demand and the renewable generation.
The VSS and plug-in electric vehicles (EVs) are coordinated by a method with two different time scales in order to execute the schedule and handle uncertainties from the load demand, outdoor environment and the renewable generation in the intra-hour adjustment stage.
A coordinate control method for a hybrid microgrid composed of various kinds of renewable energy sources was proposed in [31], where detailed models of PV modules, batteries and wind turbines were derived and the energy management strategy for whole system was developed.
To overcome the limitation, we develop a coordinate transformation method to design a complementary material, and add it into the central region of the cloak.
Based on the theory of multi-axial fatigue and critical distance, this paper first analyzes the stress state of the crankshaft under a bending moment by a coordinate transform method.
By using appropriate nonlinear state feedback and coordinate transformation method, a nonlinear system is transformed into a linear system partially or wholly, then the system controller can be designed based on the linear control method.
The algorithm is based on a coordinate transformation method.
