Size Optimization of Steel-Cored PMLSM Aimed for Rapid and Smooth Driving on Short Reciprocating Trajectory Using Auto-Tuning Niching Genetic Algorithm

Abstract

Size optimization of steel-cored permanent magnet linear synchronous motor (PMLSM) using auto-tuning niching genetic algorithm (GA) is executed for realizing rapid and smooth driving on the short reciprocating trajectory. Particularly, the dynamic constraints are newly proposed and applied for considering the running conditions of PMLSM. Furthermore, the optimally designed one is manufactured, and experimented for comparing the results with the calculated ones.Index Terms-Auto-tuning niching genetic algorithm (GA), dynamic constraints, steel-cored PMLSM.

Optimal Design of an IPMSM for HEVs Using Circular Area Movement Optimization With the Pattern Search Method

“…To verify the performance of the proposed algorithm, the CAMO was applied to two test functions with 11 peaks and 16 peaks and compared with the NGA a widely used conventional optimization algorithm that performs the same multimodal optimization as the proposed algorithm [22], [23], [24], [25]. The test function is as follows:…”

“…where 2 3 j e π α = is the vector rotating factor C. Digital PI control of the system The output of the motor velocity controller is the controlled variable increment Δ u(k). While using PI algorithm, the output incrementΔu(k) of the controller is corresponding to the position increment of the executive mechanism, rather then the actual position, therefore, it requires the executive mechanism have the function of cumulating the controlled variable increment, so that it can finish the operation to the controlled object, and this can be realized in software.…”

“…[1]. At present, the main application includes carrier aircraft launching, unmanned aircraft launching and missile/rocket launching, etc [2]. This technology combines with PMLSM, the PP-PMLSM is generated, this type of motor is mainly used in such short-term acceleration occasions, and it can produce high thrust to accelerate the objects to the desired velocity in a short period.…”
