Based on Adaptive Control in the Process of the Liquid Level Instrumentation Control System Design

Abstract:

On complex process control frequently encountered in nonlinear, inertia big, delay time longer phenomenon, is put forward based on adaptive control in the process of the liquid level instrumentation control let more model, hardware design on the input signal processing channel unit, regulators unit, output signal processing channel of unit, use control system has the deviation of the signal, may make the output of the best control signal. The control mode can not dependent on the mathematical model of the object, can be applied to many order, nonlinear, multivariate occasion. This paper provides the simulation model, and the simulation results show that the system has to level good robustness and controlling, and the controller is simple and relatively easy to implement, and has the obvious engineering application value.
