Simplified Optimum Control Method for Monoinverter Dual Parallel PMSM Drive

摘要: This paper proposes a simplified optimum control strategy for monoinverter dual parallel (MIDP) permanent magnet synchronous motor (PMSM). With reference to the PMSM unified model, two different auxiliary conditions are investigated. The first minimizes supplied inverter current, and second maximizes motor's efficiency. Their formal expressions derived by introduction of three new normalized variables, linked load conditions. Thus, tracking considerations general, parameters independent. Simplified closed analytical forms found tracking, independently under steady-state transient selection best solution is then via parameter independent look-up table, imposed through closed-loop diagram. proposed compared present state art experiments on 1400-W MIDP test bench, showing an equivalent performance, with lower computational burden.
