The design is done in three stages, the first stage is the multivariable SMC controller design that gives the L and S constants, the second stage is the static anti windup compensator design to overcome the directionality problem, and the third stage is the full order observer design than gives observer gain (K). These three stages are done with Linear Matrix Inequality (LMI). The saturation effect that leads to the inconsistency between control input and controller’s state when the control signal is saturated is called windup. This phenomenon can leads to the degradation on the system’s performance. There is also another phenomenon that need to be considered, which is when not all the states can be achieved from sensors. But, if the system is controllable and observable, this problem can be solved by using an observer. Observer with Lyapunov Stability Criterion has been successfully designed. The simulation of the observer design showed good result which shows the transient of the state error to zero at a certain time. Lyapunov stability and L2 – gain performance criteria also succeeded in reducing the effect of saturation in the system. © 2012 IEEE.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Anti-windup compensator,Anti-windup systems,Control inputs,Control signal,Full order observers,Gain performance,Input saturation,Linear matrix inequlity,Lyapunov stability,Lyapunov stability criterion,Multi variables,Multivariable sliding mode,Observer,Observer design,Observer gain,Research reports,Saturation effects,Sliding mode controller,SMC controllers,State errors,System’s performance[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Anti-Windup system static,Linear Matrix Inequality,Observer,Sliding Mode Controller[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ICSEngT.2012.6339353[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
