The aim of this project is to use variable prediction horizon nonlinear model predictive control to achieve near perfect harmonic suppression for inverters in the face of realistic and unavoidable switching delays. Other aims include further performance improvement based on the application of Kalman observer, and extension of the ideas to a variety of switching topologies and validation of the results by simulation and experiments. The intended main outcome of the project is the development of a methodology for non-interfering operation of inverters, particularly, in grid connected applications. This is expected to facilitate a further integration of renewable energy and highly efficient power utilisation. Both factors are crucial in the sustainable clean energy future.

本计画的目的是使用可变预测时域非线性模型预测控制，以达到近乎完美的谐波抑制逆变器在面对现实和不可避免的开关延迟。其他目标包括进一步的性能改进的基础上应用卡尔曼观测器，和扩展的想法，以各种开关拓扑结构和验证的结果，通过仿真和实验。该项目的预期主要成果是开发逆变器非干扰操作的方法，特别是在并网应用中。预计这将促进可再生能源和高效电力利用的进一步整合。这两个因素对可持续清洁能源的未来至关重要。
