Variable structure controllers for unstable processes
Özet
A variable structure control (VSC) method for unstable industrial processes is proposed. The proposed
control method is able to provide a highly satisfactory system performance and to tackle with robustness
issues of the processes in the presence of uncertainties. An ITAE-based numerical tuning algorithm for
acquiring optimal control parameters, and a direct auto-tuning mechanism for the proposed controller
are also provided. The performance of the proposed VSC method is illustrated on some unstable process
models including a continuous stirred tank reactor (CSTR), in order to show its effectiveness, validity and
feasibility.
