Practical inputs for maturity model of sliding mode control concepts in power electronics domain
Sliding mode control (SMC) idea has steadily remained a busy research area for more than half a century. Its market penetration in industrial products is, however, below expected line. A control idea, for its mass market penetration needs to meet, apart from control objective, multi–objective criteria ranging from its simple implementation procedure, meeting energy efficiency, cost, weight, etc. Control is inherently required in power electronics domain for control and actuation purposes to translate a particular control idea to achieve desired goal effectively. To achieve such goal, evolution in SMC has remained mostly one–dimensional - to eliminate chattering. In that process it increasingly generates complex control algorithm for power electronics to handle; whereas evolution in power electronics is searching for overall product optimisation. This article practically analyses the maturity model of SMC for its acceptability in power electronics domain.
