Title: Model Predictive Control and Estimation for Motor Drive Systems
Abstract: This talk explores motor drives research and results that leverage optimization tools to achieve high-performance control and estimation with focus on model predictive control (MPC) and optimization-based estimation (OBE). MPC is capable of addressing multidimensional nonlinear systems with state and input constraints by solving a constrained finite time optimal control problem taking 𝑁 future time steps into account. The dual, OBE, solves constrained finite time optimal estimation problem taking 𝑀 past time steps into account. High fidelity static and dynamic motor models are achieved by introducing piecewise affine (PWA) and piecewise quadratic (PWQ) maps. The resulting (nonlinear) hypersurfaces are used to describe real-world behavior including magnetic saturation, AC winding, and core loss models.
The concepts are discussed on the example of a model predictive direct torque control scheme that minimizes electromagnetic motor losses below base speed and in field weakening conditions, and does not require a dedicated MTPA or field weakening scheme. The second example is an optimization-based position and speed estimation scheme that obtains convergence guarantees, and operates about 20-100 times faster than conventional methods.
