Abstract

The paper explores the design of a normal terminal sliding mode controller (normal TSMC) for a nonlinear uncertain laboratory level tank system. The reachability condition of closed-loop system has been deduced from direct Lyapunov candidate function. The proposed design method has been compared with proportional, integral and derivative (PID) controller and typical sliding mode control (SMC). Normal TSMC and classical SMC are verified by using simulation as well as real-time experimentation while PID controller has been validated via experimental tests. The simulation and experimental result investigates that normal TSMC algorithm is more superior than PID and SMC strategies for estimated plant parameters, switching the set-point from one level to the other and internal, and external disturbances. It explores the better improvement in time-domain specifications such as response speed, settling time, overshoot in percentage, rise time and error performance indices.
