In this paper, the computer experiment cloud platform is built using big data technology, and various functions are implemented based on optimizing the platform parameters based on distributed estimation algorithms. The functional and non-functional requirements of the platform are determined, and the overall architecture design and system database design of the platform are carried out. The distributed estimation algorithm and the UDMA algorithm are used to identify the motor model, and the PID controller uses a particle swarm-based algorithm for parameter optimization. The platform system’s requirements are evaluated from environmental and performance perspectives to ensure that it meets the requirements proposed by the requirements analysis. The value of W(Si) is small, and the actual performance load of the platform remains. The performance of the platform function is good and can withstand a large amount of concurrency, and the average value of 90% response time is maintained at 5.8698s, showing an increasing trend.
